Quick Answer: The Sig Sauer P365 is still the micro-compact every other carry 9mm is measured against in 2026: it launched the 10+1 micro category in 2018. After a 2,000-round test, ours had one malfunction (an out-of-battery stoppage with Winchester White Box). The standard P365 was $499.99 at Brownells on October 29, 2026, with XRAY3 night sights in the box.

Standard configuration: 1.0 inch wide, 17.8 oz empty, 10+1 in the flush magazine (12+1 or 15+1 with extended magazines), and two 10-round magazines in the box. Trigger pull averaged 5.5 pounds with a clean wall and short reset. Accuracy at 15 yards from a rest held 2.8 inches with Federal HST 124-grain. The XRAY3 night sights are genuinely good, and Sig now sells optics-ready P365s too. The aftermarket is second only to Glock.

The biggest mistake P365 buyers make is buying the gun without committing to the 500-round practice protocol. Micros bite, trigger resets are short, and the sight radius is on a 3-inch slide; budget at least 500 rounds of dedicated practice with your chosen carry load before betting your daily defense on it.

For a carry load, our Sig V-Crown review clocked 365 V-Crown 9mm at 1,070 fps from a P365, 20 fps over Sig’s box figure.

Quick Take

The Sig Sauer P365 is one of those rare guns that actually changed an entire product category. When it dropped in 2018, nobody believed you could stuff 10+1 rounds of 9mm into a pistol this small. Every micro-compact that followed, from the Springfield Hellcat to the Shield Plus, exists because Sig proved it could be done.

After putting 2,000 rounds through my P365, I can tell you the hype is earned. This is a gun that shoots bigger than it looks, carries lighter than you’d expect, and runs reliably enough to bet your life on. The XRAY3 night sights that come standard are better than the aftermarket sights most people bolt onto their carry guns.

Is it perfect? No. The original SKU lacks an optics cut, the grip is snug if you have bear paws for hands, and competitors have caught up on capacity. But at $499.99 street with night sights included, the P365 remains the standard against which every pocket-sized 9mm is measured. It has been one of America’s best-selling handguns since it launched.

Best For: Everyday concealed carry, pocket carry, appendix IWB carry, shooters who want maximum capacity in the smallest possible package. If you’re looking at the full P365 family, check out our complete P365 models breakdown to find the right variant for you.

Why Sig Built the P365 This Way

To understand the P365, you need to understand what the concealed carry market looked like before it arrived. In 2017, your options for a pocket 9mm were the Glock 43 (6+1), the S&W Shield (7+1/8+1), and the Ruger LC9s (7+1). If you wanted double-stack capacity, you carried something much larger. That was just how it worked. Physics said you couldn’t fit more rounds into a gun that small.

Sig’s engineers disagreed. The trick was a modified double-stack magazine design that tapered to a single-stack feed geometry at the top. This let the P365 hold 10 rounds in a flush-fit magazine while keeping the grip only 1.0″ wide. When Sig unveiled it at SHOT Show 2018, people genuinely didn’t believe the specs until they held the gun and counted the rounds.

The other smart move was including XRAY3 night sights from the factory. Most guns in this price range ship with basic three-dot sights that you’ll immediately want to replace. Sig knew the P365 would be a carry gun, so they included sights that actually work in low light. The tritium front dot inside a bright green ring is one of the best sight pictures available on any handgun at any price.

Then there’s the FCU (Fire Control Unit). The P365’s serialized component is a removable chassis that houses the trigger group. This makes the gun modular. You can swap grip modules, move your FCU between different P365 configurations, and customize without buying a whole new firearm. It’s the same concept Sig used on the P320, scaled down for the micro-compact platform. This modularity is a big part of why the P365 family has grown to 10+ variants.

Sig didn’t just build a small gun. They built a platform. And eight years later, that platform is still the one everyone else is trying to beat.

Features and Technical Deep Dive

Frame and Construction

The P365’s polymer frame is reinforced with a stainless steel internal chassis (the FCU). The frame itself feels solid for its weight class, with no flex or creaking when you grip it hard. Sig uses an aggressive grip texture that works well without being sandpaper-abrasive against your skin during summer carry.

The stainless steel slide wears Sig’s Nitron finish, which has held up well through my testing. I’ve carried this gun through sweat, rain, and general neglect without seeing corrosion. The slide serrations are front and rear, with a good depth that gives you purchase during press checks or malfunction drills. At 17.8 ounces unloaded, the P365 sits in that sweet spot where it’s light enough to forget you’re carrying but heavy enough to absorb some recoil.

Sights and Optics

The XRAY3 sights deserve their own section because they’re genuinely one of the P365’s best features. The front sight has a tritium insert surrounded by a bright green photoluminescent ring. In daylight, it’s a crisp green circle. In low light, the tritium glows. At night, it’s unmistakable. The rear sights are blacked out with two smaller tritium inserts.

I’ve used these sights in indoor ranges, outdoor ranges at dusk, and dry-fire sessions in my dark hallway. They work. I’ve replaced factory sights on dozens of handguns over the years, but the XRAY3s are staying put. This is hundreds of dollars worth of sight quality that comes in the box.

The one limitation on the original P365 SKU is the lack of an optics cut. Sig now sells an optics-ready P365 (365-9-BXR3P, $499.99 at EuroOptic on October 29, 2026) along with the P365X, XL and XMACRO. For a carry gun used with iron sights, I don’t consider this a real drawback. But if a dot is non-negotiable for you, buy one of the cut versions.

Trigger

The P365 trigger is a flat-faced design with a built-in safety blade. Take-up is smooth with a defined wall, and the break is clean at roughly 5.5 to 6 pounds on my Lyman gauge. Reset is short and tactile. You can feel and hear it click back into position.

Is it a match trigger? No, and it shouldn’t be on a carry gun. But it’s one of the better stock triggers in the micro-compact class. The flat face gives you consistent finger placement, and the break point is predictable enough for precise shooting at defensive distances. I’ve seen guys shoot sub-3-inch groups at 15 yards with this trigger, and I can reliably hold a 4-inch group at that distance if I do my part.

Ergonomics and Controls

The P365 fits in your hand like a gun that has no business being this comfortable. At 1.0″ wide, it should feel like gripping a playing card. Instead, the grip geometry and texturing create a surprisingly secure hold. My hands are medium-sized, and I get a full firing grip with the flush 10-round magazine. The extended 12-round magazine adds about half an inch of grip length and is even better.

The slide stop is small but functional. Magazine release is reversible and positioned well. The takedown lever is standard Sig fare. If you’ve handled any modern Sig pistol, you’ll feel at home immediately. One note for large-handed shooters: the flush magazine will leave your pinky dangling. The 12-round extended mag fixes this, and it only adds minimal bulk to the overall package.

Recoil management is better than you’d expect from a sub-18-ounce 9mm. The bore axis is relatively low, and the grip angle does a good job of directing recoil into the web of your hand rather than flipping the muzzle up. It’s snappier than a compact or full-size gun, obviously. But it’s manageable enough for fast follow-up shots at defensive distances. I can run controlled pairs into an 8-inch circle at 7 yards all day.

Magazines and Capacity

The standard P365 ships with two flush-fit 10-round magazines; some packages swap one for an extended magazine. The magazines are steel-bodied with polymer baseplates and have been completely reliable in my testing. Loading the last round into a full 10-round mag is stiff, as it should be with a quality magazine spring. A Maglula UpLULA loader works if your thumbs protest.

Sig also offers 12-round extended magazines and the P365 XL’s 15-round magazines, which fit the P365 and stick out below the grip. The XMACRO uses its own 17-round magazine. The magazine ecosystem is one of the P365 platform’s biggest strengths: between Sig factory mags and aftermarket options, you can set capacity and grip length to suit exactly how you carry.

One practical tip: I carry with the 12-round magazine in the gun and a spare 12-rounder in a pocket. That gives me 13+12 = 25 rounds on my person, which is more than most people carry in a full-size pistol. For a gun that fits in a pocket, that level of capacity is remarkable.

2,000 Round Range Test

I put 2,000 rounds through this P365 over a period of several months, mixing range sessions with carry days in between. I intentionally ran it with different ammo types, different magazines, and varying cleaning schedules to simulate real-world carry conditions. Here’s how it broke down.

Ammo Log

• Federal American Eagle 115gr FMJ: 600 rounds
• Blazer Brass 115gr FMJ: 400 rounds
• Winchester White Box 115gr FMJ: 300 rounds
• Fiocchi 124gr FMJ: 200 rounds
• Speer Gold Dot 124gr +P JHP: 150 rounds
• Federal HST 124gr JHP: 150 rounds
• Hornady Critical Defense 115gr FTX: 100 rounds
• Sig V-Crown 124gr JHP: 100 rounds

Break-In Period

The P365 needed zero break-in. It ran from round one. Some micro-compacts need 200 rounds to smooth out, and I always plan for that with a new gun. The P365 didn’t ask for it. The first 200 rounds were a mix of Federal American Eagle and Blazer Brass, and everything cycled, fed, extracted, and ejected without a single hiccup.

Slide lockback on empty was consistent with all magazines from the start. I deliberately loaded magazines to full capacity (no downloading to 9 rounds to “be safe”) and had no feeding issues. The recoil spring felt properly calibrated right out of the box. I also ran 50 rounds of Speer Gold Dot early on to confirm defensive ammo reliability before committing this gun to carry duty. All 50 fed and cycled without issue.

Reliability Testing

Across 2,000 rounds, I had exactly one malfunction: a failure to fully go into battery around round 1,400 with Winchester White Box. The slide was about 1/16″ out of battery. A tap on the back of the slide seated it, and it didn’t happen again. I’m inclined to blame the ammo rather than the gun, as Winchester White Box is known for inconsistent case dimensions.

That’s a 99.95% reliability rate. For a micro-compact running mixed ammo with varying cleaning schedules, that’s outstanding. I went as long as 500 rounds between cleanings with no issues. The gun got dirty, but it kept running. Hollow points fed flawlessly. The Speer Gold Dots and Federal HSTs, which have aggressive hollow point profiles, never hung up on the feed ramp.

I also tested with the flush 10-round, extended 12-round, and a 15-round Sig magazine. All three ran without issues. Magazine insertion was positive on all three, and they dropped free cleanly on release.

Accuracy Testing

Accuracy testing from a bench rest at 15 yards produced some genuinely impressive groups for a 3.1″ barrel. Federal HST 124gr turned in the best group at 2.8 inches (five shots). Speer Gold Dot 124gr +P was close behind at 3.1 inches. The budget stuff (Blazer Brass 115gr) opened up to about 4 inches, which is still plenty for a defensive handgun.

At 7 yards, which is more realistic for a defensive scenario, I was consistently holding 2-inch groups shooting at a moderate pace. At 25 yards (pushing it for this gun), I could keep everything on an 8-inch paper plate shooting slow fire. The XRAY3 front sight makes precise aiming surprisingly easy for a micro-compact.

The P365 isn’t a target pistol, and nobody buys one expecting to shoot bullseye matches. But it’s more accurate than most shooters will be able to exploit, especially under stress. For quality defensive ammo, you can expect 3-inch groups at 15 yards, and that’s more than adequate for its intended role.

Post-Test Inspection

After 2,000 rounds, I field-stripped the P365 and inspected the internals. The barrel showed normal wear patterns with no unusual marks. The feed ramp was smooth with some carbon buildup but no gouging. The recoil spring assembly still had good tension. The striker channel was clean, and the striker itself showed no signs of the issues that plagued early production models.

The frame rails showed minimal wear. The slide-to-frame fit was still tight with no perceptible loosening. The Nitron finish on the slide had some minor holster wear on the edges, which is cosmetic and expected. Overall, the gun looks like it has another 10,000+ rounds in it before anything needs attention.

Performance Testing Results

Reliability: 9/10

One malfunction in 2,000 rounds, and that one was almost certainly ammo-related. The P365 ate everything I fed it, from bargain-bin range ammo to premium defensive loads. Magazine reliability was perfect across all three magazine sizes. This is the level of reliability you need from a gun you’re trusting your life to.

The reason it’s a 9 and not a 10 is the early production history. Yes, those issues are resolved. Yes, current production guns are excellent. But Sig had a rough first year with the P365, and intellectual honesty requires acknowledging that. If you’re buying a new P365 today, reliability should not be a concern.

Accuracy: 8/10

Sub-3-inch groups at 15 yards from a 3.1″ barrel is legitimately impressive. The P365 outshot my expectations and outshot several of its competitors in back-to-back testing. The XRAY3 sights contribute significantly here. A gun is only as accurate as your ability to aim it, and these sights make aiming easy.

It loses points only because physics is physics. A 3.1″ barrel with a short sight radius will never match a compact or full-size gun for pure accuracy. If you need a tighter-shooting P365, the XL with its 3.7″ barrel closes the gap considerably.

Ergonomics and Recoil: 9/10

The P365 punches above its weight class in ergonomics. The grip geometry is excellent, recoil is manageable for its size, and the controls are well-placed. I can shoot this gun for extended range sessions without the hand fatigue that some micro-compacts inflict. The flat-faced trigger is a nice touch that aids in consistent shot placement.

The only ergonomic knock is the flush magazine and small grip for larger hands. But that’s inherent to the micro-compact category, and Sig mitigates it well with the 12-round and 15-round magazine options. If grip size is your primary concern, the P365 XL or Glock 43X might be better fits.

Fit, Finish and QC: 9/10

This is a well-made gun. The stainless steel slide, Nitron finish, XRAY3 sights, and overall assembly quality reflect Sig’s manufacturing standards. There are no tool marks, no rough edges, and no cosmetic issues on my sample. The slide-to-frame fit is tight without being sticky. Magazine fit and function is precise.

Sig’s quality control has improved dramatically since the P365’s launch. The early guns had legitimate issues that damaged trust. The current production guns I’ve handled (including this one) show none of those problems. Sig learned from those mistakes, and today’s P365 reflects that. The Nitron finish on the slide is particularly well-done. It’s not just cosmetic; the stainless steel underneath means even if the coating wears, you won’t see rust.

Known Issues and Common Problems

Early Production Striker and Primer Drag (2018)

Let’s address the elephant in the room. When the P365 first shipped in 2018, some early production guns had reports of primer drag (the striker dragging across the primer during cycling) and broken strikers. This was a real issue, and Sig addressed it with updated internal components. If you bought a P365 in the first six months of production, you may have experienced this.

Here’s the important context: this is ancient history. Sig updated the parts in 2018, and a P365 bought new today has eight years of production refinement behind it. You’ll still see the early reports referenced, and you deserve the full picture. But it should not factor into a 2026 purchasing decision.

Small Grip for Large Hands

If you wear XL gloves, the P365’s grip will feel small with the flush 10-round magazine. Your pinky will hang off the bottom. The 12-round extended magazine helps, but it changes the gun’s overall profile. For shooters with large hands who want the P365 platform, the P365 XL is the better option. It gives you a longer grip, longer barrel, and optics cut while keeping the same basic design.

No Optics Cut on Base Model

The original P365 SKU does not come optics-ready. In 2026, with red dots becoming the standard for carry guns, that matters. Sig’s answer is the optics-ready P365 (365-9-BXR3P), the P365X (same size, longer grip) and the P365 XL (longer slide). If you’re buying specifically for iron sights, this is a non-issue. If you’re on the fence about optics, buy a cut version.

Capacity Advantage Narrowed

When the P365 launched, 10+1 in a micro-compact was unmatched. Today, the Springfield Hellcat offers 11+1, and the S&W Shield Plus matches 10+1 in a similar footprint. The P365 no longer owns the capacity crown. It’s still competitive, but the gap that made it revolutionary has closed. The P365’s advantages now lie in its overall refinement, sights, modularity, and ecosystem rather than raw round count.

Competitor Comparison

On October 29, 2026 the P365 was $499.99 at Brownells. The Glock 43X MOS was $484 at Midway USA, the Springfield Hellcat OSP $554.99 at Midway USA, the S&W Shield Plus $384.99 at Bereli and the Taurus GX4 $279.99 at Palmetto State Armory. The P365 sits mid-pack on price and is the only one of the five with night sights standard.

Glock 43X MOS (from $484)

The Glock 43X MOS is the P365’s most direct competitor. It offers a 10+1 capacity with a slightly larger grip that accommodates bigger hands. The MOS version comes optics-ready. The 43X is longer and taller than the P365, which makes it a better shooter but a slightly bulkier carry gun. Glock’s reliability reputation is rock-solid, and the aftermarket is enormous.

The tradeoff is clear: the 43X is a better range gun and fits larger hands better, while the P365 is more concealable and includes better factory sights. Glock’s factory plastic sights are genuinely awful compared to the XRAY3s. If you prioritize shootability and plan to add a red dot, the 43X MOS deserves serious consideration. If concealment and out-of-the-box readiness matter more, the P365 wins.

Springfield Hellcat OSP (from $554.99)

The Springfield Hellcat was the first gun to directly challenge the P365’s capacity record, offering 11+1 in a similarly sized package. It also came with an optics-ready version (the OSP) from early in its lifecycle. The Hellcat’s U-Dot sight system is good, though I prefer the XRAY3s. Recoil is snappier on the Hellcat, likely due to its slightly lighter weight and more aggressive bore axis.

The Hellcat is a solid gun, and the 11+1 capacity gives it a one-round advantage over the P365’s flush magazine. But in my experience, the P365 feels more refined. The trigger is better, the sights are better, and the recoil impulse is more manageable. The Hellcat wins on capacity and optics availability on the base model. The P365 wins on everything else.

S&W M&P Shield Plus (from $384.99)

The Shield Plus is Smith & Wesson’s answer to the micro-compact capacity wars, offering 10+1 (flush) or 13+1 (extended). It’s slightly thicker than the P365 at 1.1″ wide but brings a familiar M&P grip angle and trigger feel that Shield owners already know. At $384.99 at Bereli on October 29, 2026, $115 less than the P365, it’s the value play in this comparison.

The Shield Plus is a good gun at a great price. Where it falls short is the factory sights (basic white dots) and the lack of the P365’s modular FCU system. If you’re budget-conscious and don’t care about night sights or modularity, the Shield Plus saves you money and gives you comparable capacity. If you want the best out-of-the-box experience, the P365 justifies the price premium.

Taurus GX4 (from $279.99)

The Taurus GX4 is the budget option in this space, and it’s surprisingly competitive. It offers 11+1 capacity in a P365-sized package for $279.99 at Palmetto State Armory (October 29, 2026). Build quality has improved significantly from older Taurus designs. The trigger is acceptable, and reliability has been good.

The GX4 makes sense if budget is your primary concern. At $220 less than the P365, it frees up money for ammo and training. But you give up the XRAY3 sights, the Nitron-finished stainless slide, the FCU modularity, and the depth of the P365’s aftermarket. For a first carry gun on a tight budget, the GX4 is worth considering. For a “buy once, carry forever” gun, I’d stretch for the P365.

Parts, Accessories and Upgrades

The P365’s aftermarket is one of the largest in the handgun world. Because millions of these guns are in circulation, every major accessory manufacturer makes P365-specific products. Here are the upgrades that actually matter.

Upgrade Category	Recommended Component	Why It Matters	Cost Estimate
Holster	Quality kydex AIWB (Tier 1, T.Rex, Tenicor)	The right holster makes or breaks a carry gun this small	$60-$120
Extended Magazine	Sig factory 12-round or 15-round	Extra capacity and better grip, stick with Sig factory mags	$35-$50
Grip Module	Sig WCP or aftermarket (Icarus, Armory Craft)	FCU modularity lets you swap grips for different textures and sizes	$40-$200
Trigger	Sig flat trigger (factory) or Armory Craft dual adjustable	Stock trigger is good, but aftermarket options refine the pull	$50-$80
Magazine Release	Armory Craft extended mag release	Slightly larger surface area for faster reloads	$25-$35
Night Sights	Keep the factory XRAY3s	Seriously, the factory sights are that good. Save your money	$0

You can find most of these upgrades, and the P365 itself, at EuroOptic.

My honest recommendation: don’t change anything right away. Shoot the gun stock for at least 500 rounds. The P365 is excellent out of the box, and most “upgrades” are solutions looking for problems. A good holster and extra magazines are the only must-buys. Everything else is optional refinement.

Carrying the P365

This is where the P365 earns its reputation. At 17.8 ounces and 1.0″ wide, this gun flat-out disappears. I’ve carried it appendix IWB in a kydex holster under a t-shirt with zero printing. I’ve carried it in a pocket holster in cargo shorts. I’ve carried it at 4 o’clock under a flannel. Every method works because the gun is just that small and light.

The width is the secret weapon. At 1.0″, the P365 is thinner than most smartphones in a case. It doesn’t create the telltale bulge that wider guns produce. Combined with the short overall length and low weight, you genuinely forget it’s there. I know that sounds like marketing copy, but I’ve carried full-size guns, compacts, and sub-compacts. The P365 is in a different league for all-day comfort.

Summer carry is where the P365 really shines over larger alternatives. When the temperature hits 90 degrees and you’re in a t-shirt and shorts, most compact pistols become difficult to conceal. The P365 handles summer wardrobe effortlessly. I’ve carried it in athletic shorts with a good belt and holster combo. In a tank top with the right appendix setup. The 5.8″ overall length and 4.3″ height give you enough gun to get a solid grip on the draw without enough bulk to print through light clothing.

For holster selection, you have hundreds of options. Every major holster maker produces P365-specific models. I’d recommend investing in a quality kydex appendix holster with a wing/claw for maximum concealment. The gun is small enough that you don’t need a fancy holster to hide it, but a good one makes it feel like you’re carrying nothing at all. For more carry gun options, see our best concealed carry handguns guide.

The P365 Family: Which One Is Right for You?

The standard P365 reviewed here is just the starting point. Sig has built an entire family around this platform, and it can get confusing. Here’s the quick version: the P365 is the smallest and most concealable. The P365X adds an optics cut and a slightly longer grip. The P365 XL gives you a longer slide, barrel, and grip with optics capability. The P365 XMACRO goes full compact-size with a 17+1 capacity.

All of them share the same FCU, so you can literally swap your serialized fire control unit between grip modules. Buy a P365, and you’re buying into an ecosystem. We have a full breakdown of every variant in our P365 models explained guide if you want to compare them side by side.

For most people, the standard P365 or the P365X is the sweet spot. The standard is best for maximum concealment. The X is best if you want an optics cut without adding length. The XL is for shooters who prioritize shootability over absolute concealment. And the XMACRO is honestly a compact gun wearing a P365 badge.

Who Should NOT Buy the Sig P365

• Shooters with large hands who won’t add an extended magazine; the Glock 43X MOS ($484) has a longer grip.
• Red dot users buying the original SKU; get the optics-ready 365-9-BXR3P instead.
• Buyers on the tightest budget; the Taurus GX4 ($279.99) holds 11+1 for $220 less.
• Anyone who wants 11+1 flush; the Hellcat and GX4 hold one more round.
• Range-only shooters; a compact like the P365 XL shoots softer.

Sig P365 by the Numbers

• 2,000 rounds of 8 loads, 1 malfunction (99.95%)
• 2.8 in best 5-shot group at 15 yards (Federal HST 124gr)
• 10+1 flush, 17.8 oz, 1.0 in wide, 3.1 in barrel
• 5.5 lb average trigger pull on our Lyman gauge
• $499.99 street (October 29, 2026); launched in 2018

The Verdict

The Sig Sauer P365 earned its place as one of America’s best-selling handguns. After 2,000 rounds, I’m more convinced of that than before I started testing. This is a gun that does everything a concealed carry pistol needs to do: it’s small enough to carry every day, reliable enough to trust with your life, accurate enough for defensive use, and built well enough to last. The XRAY3 night sights alone set it apart from nearly everything in its class.

Is it the perfect gun? No. The original SKU’s lack of an optics cut is a real limitation in 2026 (buy the optics-ready version if you want a dot). The grip is small for large-handed shooters. And the capacity advantage that made it revolutionary in 2018 has been matched by competitors. But perfection isn’t the standard. The standard is whether this gun does its job well, and the P365 does its job exceptionally well.

What separates the P365 from its competitors isn’t any single feature. It’s how everything works together. The capacity, the sights, the size, the weight, the trigger, the reliability, the modularity, the aftermarket. No other micro-compact nails all of those categories simultaneously. Some beat it in one area (the Hellcat on capacity, the Shield Plus on price, the 43X on grip size), but none beat it across the board.

If you’re looking for your first carry gun, the P365 should be at the top of your list. If you’re looking to upgrade from an older single-stack like a Ruger LC9 or original Shield, the P365 is a night-and-day improvement in every measurable way. And if you’re a seasoned carrier who wants a gun that just works, the P365 has eight years of proven performance behind it. There’s a reason Sig Sauer keeps selling millions of these. The gun speaks for itself.

Final Score: 9.0/10

Best For: Everyday concealed carry, appendix IWB, pocket carry, anyone who wants maximum capacity in a minimum-size package. Ideal for first-time carriers and experienced shooters alike. If you’re choosing between Sig carry guns, the P365 is the starting point for good reason.
