Glock 19X Pros and Cons

Glock 19X: Best Prices

Glock 19X Quick Take

I put 1,500 rounds through the Glock 19X over the course of two months. Federal HST 147gr, Speer Gold Dot 124gr, Blazer Brass 115gr, Winchester White Box, Hornady Critical Duty 135gr, and several hundred rounds of whatever was cheapest at the time. Zero malfunctions. Not one failure to feed, failure to eject, or light primer strike. That is the headline with any Glock, and the 19X is no exception.

The 19X is the pistol Glock submitted for the U.S. Army’s Modular Handgun System trials. It lost to the Sig Sauer P320 (which became the M17/M18), and Glock released it commercially in 2018. The concept is simple: take the compact slide from the Glock 19 and mate it to the full-size frame of the Glock 17. You get a shorter barrel for easier holstering and concealment with a full-length grip that fills your hand and holds 17 rounds.

That combination turns out to be excellent for shooting comfort. The full grip gives you a rock-solid purchase that makes recoil management noticeably easier than a standard G19. The Coyote Tan frame grew on me after a week. It stands out in a sea of black polymer pistols, and the nPVD finish has proven tougher than I expected.

Best For: Duty use, home defense, and open carry where grip length is not a concealment concern. The 19X rewards shooters who want maximum grip real estate without the full-length slide of a G17. If you plan to run an optic, look elsewhere. If you want a tank-reliable Glock that feels great in the hand and comes with night sights and 19-round mags, the 19X still delivers.

Firearm Scorecard

The MHS Backstory: How the 19X Came to Be

The Glock 19X has one of the more interesting origin stories in the handgun world. In 2015, the U.S. Army launched the Modular Handgun System (MHS) competition to replace the aging Beretta M9 as the standard sidearm for all branches. The requirements called for a modular, striker-fired pistol in 9mm with an accessory rail, ambidextrous controls, and a manual safety option.

Glock submitted a pistol built specifically for the trials. It married the compact slide of the G19 to the full-size frame of the G17, added Glock’s first-ever Coyote Tan finish, included a lanyard loop for military retention requirements, and shipped with the Glock Marksman Barrel. It also featured an ambidextrous slide stop and a smooth magazine well with no finger grooves, features that would also appear on the Gen 5 lineup later that year.

Sig Sauer won the MHS contract with the P320, which became the M17 (full-size) and M18 (compact). The decision was controversial, and Glock filed a formal protest that was ultimately dismissed. Rather than shelve the design, Glock made the smart move of releasing it to the commercial market in January 2018 as the 19X. It was the first “crossover” Glock: compact slide, full-size frame.

The 19X sold extremely well. The crossover concept resonated with shooters who wanted more grip to hold onto without the longer sight radius and holster footprint of a full G17 slide. Glock eventually followed up with the Glock 45 in late 2018, which is essentially the 19X in black with front slide serrations and without the lanyard loop. The G45 has since become the more popular of the two, but the 19X holds its place as the original crossover that started the trend.

Competitor Comparison

The crossover/duty compact market has gotten crowded since 2018. Here is how the Glock 19X stacks up against its most direct competitors.

Glock 19X vs. Glock 19 Gen 5 MOS

The Glock 19 Gen 5 MOS is arguably the more practical choice for most buyers. It uses the same compact slide as the 19X but pairs it with a compact frame, giving you a pistol that conceals more easily. The MOS designation means it comes factory-cut for a red dot optic, which the 19X does not offer at all. Street prices overlap in the $580 to $700 range, making the Gen 5 MOS a better value when you factor in the optics compatibility.

The 19X wins on grip comfort and capacity. That full-size frame holds 17 rounds standard (19 with the included extended mags) versus the G19’s 15. The longer grip also makes the 19X noticeably easier to shoot well, especially during extended range sessions or rapid fire. If concealment is your priority, the G19 Gen 5 MOS is the smarter pick. If you want maximum shootability and do not need an optic, the 19X has the edge.

Glock 19X vs. Glock 45

This is the comparison everyone asks about, and the honest answer is that the Glock 45 is the better buy for most people. It uses the same crossover concept (compact slide, full-size frame) but adds front slide serrations, ditches the lanyard loop, and comes in standard Glock black. Street price runs $500 to $600, which is $50 to $100 less than the 19X. The G45 is also available in an MOS variant with a factory optics cut.

The 19X counters with Glock night sights as standard (the G45 ships with basic polymer sights), the Coyote Tan finish if that appeals to you, and 19-round extended magazines in the box. Night sights alone would cost $80 to $130 as an aftermarket upgrade on the G45, which narrows the price gap considerably. If you like the Coyote color and value factory night sights, the 19X still makes sense. If you just want the crossover concept at the best price with the option to add an optic, the G45 MOS is the move.

Glock 19X vs. Sig Sauer P320 M17

The Sig P320 M17 is the gun that beat the 19X in the MHS trials, and the commercial version is a strong competitor. It is fully modular (the fire control unit can move between grip modules), comes factory optics-ready with a rear sight plate, includes a manual safety, and accepts 17-round or 21-round magazines. Street price runs $600 to $700.

I have shot both extensively. The M17 has a better trigger out of the box, feels slightly larger in the hand, and the modularity is genuinely useful if you like swapping between frame sizes. The 19X is more reliable in my experience (the early P320 had well-documented drop safety issues that Sig fixed with the voluntary upgrade), shoots flatter thanks to lower bore axis, and benefits from the massive Glock aftermarket. Both are excellent duty pistols. The Sig offers more features for the money. The Glock offers more proven reliability and a deeper ecosystem.

Glock 19X vs. Glock 19 Gen 6

The Glock 19 Gen 6 is Glock’s newest generation compact and brings genuine improvements over the Gen 5. Updated internals, refined ergonomics, and the latest iteration of the Glock platform. At $600 to $700 street, it is priced similarly to the 19X. For details on what changed in the Gen 6, see our breakdown.

The Gen 6 is a compact pistol with a compact frame, so it conceals better than the 19X. The 19X still offers the full-size grip advantage, standard night sights, and the 19-round magazine option. If you are choosing between these two for duty or home defense, the 19X’s grip and capacity edge matters. For everyday carry where printing is a concern, the Gen 6 G19 is the more versatile pistol.

Glock 19X vs. S&W M&P 2.0 Full Size

The Smith & Wesson M&P 2.0 Full Size in 9mm is a lot of gun for the money. At $480 to $600 street, it undercuts the 19X by $50 to $100 and comes with a better factory trigger, four interchangeable palm swell inserts, aggressive grip texture, and 17+1 capacity. The M&P 2.0 also comes in an optics-ready variant.

The 19X’s advantages here are the Glock name, the Glock aftermarket, and the nPVD finish quality. The M&P trigger is genuinely better from the factory, with a crisper break and shorter reset. If brand loyalty is not a factor and you want maximum value in a full-size 9mm, the M&P 2.0 is hard to beat. If you are already invested in the Glock ecosystem with holsters, magazines, and muscle memory, the 19X keeps you in that world.

Technical Deep Dive

Frame and Grip

The Glock 19X frame is the Gen 5 G17 frame in Coyote Tan polymer. That means you get the full-size grip length (5.47″ with magazine inserted), no finger grooves (a Gen 5 change that most shooters welcomed), and a flared magazine well that makes reloads faster and smoother. The grip texture is Glock’s standard rough texture, identical to what you find on the Gen 5 G17 and G19. It provides adequate purchase without being abrasive against skin during concealed carry.

The most distinctive feature on the frame is the lanyard loop at the base of the grip. This was a military requirement for the MHS trials. In civilian use, it serves no practical purpose for most people. It does not interfere with shooting or holstering, but it adds a visual element that some shooters find unnecessary. You can remove it with a punch and a few minutes of work if it bothers you.

Ergonomically, this is where the 19X shines. Wrapping your hand around that full-size grip while looking down at a compact slide feels right. You get all four fingers plus a solid palm swell, and the natural point of aim is excellent. Compared to holding a standard G19, the 19X feels planted. The extra grip length provides a noticeable improvement in recoil control that I could feel during rapid fire drills.

Slide and Finish

The 19X slide is the same dimensions as the Glock 19 Gen 5 slide, coated in Glock’s nPVD (Physical Vapor Deposition) finish in Coyote Tan. This finish provides good durability and corrosion resistance while enabling the distinctive Coyote color that standard nDLC cannot achieve. After two months of daily handling, holster wear, and a few accidental drops onto gravel, my 19X slide shows minimal wear marks. The finish holds up.

Early 19X models shipped without front slide serrations, which was a legitimate criticism. Press checks require gripping the front of the slide, and without serrations, you are relying on friction alone. The 19X has never received front serrations in any production run. This is a permanent design difference between the 19X and the Glock 45, which does include them. Check before you buy, especially if you are purchasing from older dealer stock.

The slide also lacks an optics cut. In 2018, that was less of an issue. In 2026, it is a dealbreaker for many shooters. Red dots on pistols have gone from niche to mainstream, and paying $550 or more for a pistol that cannot accept a factory-mounted optic is a tough sell. You can have the slide milled by a third-party shop for $100 to $200, but that adds cost and downtime to a pistol that should have offered this from the factory.

Barrel

The 4.02-inch Glock Marksman Barrel (GMB) features an improved rifling profile with a tighter, more precise bore compared to older Glock barrels. Glock introduced the GMB with the Gen 5 series, and the 19X was one of the first pistols to use it. The barrel has an nPVD coating that matches the slide finish and adds corrosion resistance.

The GMB makes a real difference in accuracy. From a bench rest at 25 yards, I consistently shot 2-inch groups with Federal HST 147gr and 2.3-inch groups with Speer Gold Dot 124gr. That is notably better than what I have seen from older Glock barrels. The crown is cleaner, the bore is more consistent, and the overall barrel quality is a genuine step up. It is not match-grade, but it is excellent for a duty pistol.

Trigger

The 19X uses Glock’s Safe Action trigger system. My example breaks at approximately 5.5 pounds with a moderate amount of take-up, a discernible wall, and a reasonably clean break. Reset is short and tactile. It is a Glock trigger. If you have shot any Gen 5 Glock, you know exactly what to expect.

The trigger is safe, predictable, and consistent. It is not exciting. The triggers on the Sig P320 M17 and S&W M&P 2.0 feel more refined from the factory. But the Glock trigger’s greatest strength is its simplicity and reliability. It works the same way every single time, cold or hot, dirty or clean. For a duty or defensive pistol, that consistency matters more than a crisp competition break. Aftermarket options from Apex, Overwatch Precision, and Johnny Glock can improve the feel significantly if the stock pull bothers you.

Sights

Here is where the 19X separates itself from most factory Glocks. It ships with Glock night sights as standard equipment. These are steel sights with tritium inserts that glow in low-light conditions. On most other Glocks, you get basic polymer Glock Marksman sights that are nearly useless in dim lighting. The 19X’s factory night sights are a genuine advantage and save you $80 to $130 versus buying aftermarket tritium sights for a standard Glock.

The sight picture is a standard three-dot layout with a white-outlined rear and a single front dot. They are perfectly functional for defensive and duty use. They are not the sharpest night sights on the market. Trijicon HD XR and Ameriglo Bold sights offer better contrast and visibility. But for factory-included sights, the 19X’s are well above average. This is one of the strongest arguments for choosing the 19X over the Glock 45, which ships with inferior polymer sights.

Magazine System

The 19X ships with three magazines: one standard 17-round magazine and two extended 19-round magazines. That is a generous package compared to most Glocks, which ship with two or three standard magazines. The 19-round magazines add about half an inch to the grip length and use a polymer baseplate extension. They feed reliably and I ran both of mine extensively during testing without a single issue.

Because the 19X uses a full-size G17 frame, it accepts all Glock 17 magazines: standard 17-round, 19-round extended, and even the 24-round and 33-round extended magazines. It will not accept Glock 19 15-round magazines because they are too short for the longer grip. This is worth knowing if you are coming from a G19 and hoping to share magazines. You will need to buy G17-pattern mags.

At the Range: 1,500 Rounds Tested

[IMAGE: Glock 19X on a shooting bench with brass casings scattered nearby and paper targets in the background. Alt text: Glock 19X at the range during 1500 round test with spent brass and targets]

I ran the 19X through a 1,500-round test across six range sessions over eight weeks. The goal was to test reliability with a wide variety of ammunition, evaluate practical accuracy at defensive distances, and see how the nPVD finish held up to sustained use. I ran the gun bone stock with no modifications for the entire test.

For practice ammunition, I used Blazer Brass 115gr FMJ, Winchester White Box 115gr FMJ, and whatever bulk 9mm I could find on sale. For defensive loads, I tested Federal HST 147gr, Speer Gold Dot 124gr, and Hornady Critical Duty 135gr. Every single round cycled without issue. 1,500 rounds, zero malfunctions. I cleaned the gun once at the 750-round mark and it was still running smooth at 1,500.

Recoil management is where the 19X truly stands out. That full-size grip gives you so much more purchase than a standard G19 that the difference is immediately obvious. Split times during bill drills at 7 yards averaged 0.20 to 0.23 seconds, which is fast for a service-size pistol. I could consistently keep all shots inside a 4-inch circle at 10 yards shooting aggressively and inside a 6-inch circle at 15 yards at speed.

The heavier defensive loads felt best in this gun. Federal HST 147gr produced the flattest recoil impulse and the tightest groups. Speer Gold Dot 124gr was close behind. Hornady Critical Duty 135gr, which is a barrier-blind load designed for duty use, also performed well and would be my top recommendation for anyone carrying the 19X professionally. The lighter 115gr practice ammo ran fine but produced a snappier recoil impulse, as expected.

Performance Testing Results

Ammunition	5-Shot Group @ 25 yds	Avg Velocity (fps)	Malfunctions
Federal HST 147gr JHP	2.0″	978	0
Speer Gold Dot 124gr JHP	2.3″	1,058	0
Hornady Critical Duty 135gr FlexLock	2.5″	1,010	0
Blazer Brass 115gr FMJ	2.8″	1,112	0
Winchester White Box 115gr FMJ	3.1″	1,098	0
Federal American Eagle 124gr FMJ	2.6″	1,042	0

The GMB barrel delivered its best groups with heavier bullets, which is consistent with what I have seen from other Glock 19-length barrels. The 2-inch group with Federal HST 147gr at 25 yards from a bench rest is excellent for a duty pistol. That load also produced the softest felt recoil, making it my preferred carry round in the 19X.

Known Issues and Common Problems

The 19X has been on the market since 2018 and has a well-documented track record. Here are the issues worth knowing about.

No optics cut. This is the biggest knock against the 19X and the reason many shooters skip it entirely. In a market where even budget pistols come with factory optics cuts, the 19X’s bare slide feels like a relic. If you want a red dot, you will need to send the slide out for milling ($100 to $200 plus shipping and downtime) or buy a different pistol. The Glock 45 MOS solves this problem if you want the same crossover concept with optics capability.

Coyote Tan holster compatibility. Most Kydex holsters are molded for standard black Glocks. The 19X has the same external dimensions as a G45 or G17 frame, so fit is not an issue. But finding a holster that color-matches the Coyote Tan finish limits your options. This is purely cosmetic, but it bothers some people enough to mention.

Magazine incompatibility with G19 mags. If you are transitioning from a Glock 19, your existing 15-round magazines will not seat properly in the 19X. The longer grip extends past the bottom of a G19 magazine, leaving a gap. You need G17-length magazines. This catches some buyers off guard, so plan accordingly.

No front slide serrations. No 19X production run has ever included front slide serrations. The Glock 45, released later in 2018, addressed this omission, but older stock still circulates at some dealers. If front serrations matter to you (they should), verify before purchasing.

Lanyard loop snags. A small number of owners report the lanyard loop catching on clothing or range bags during the draw stroke. I did not experience this personally, but the loop sits in a spot where it can interfere depending on your holster setup and wardrobe. Again, it can be removed with a punch if it becomes a problem.

Parts, Accessories, and Upgrades

The 19X benefits from the Glock Gen 5 aftermarket, which is enormous. Here are the upgrades I think are most worthwhile for this specific pistol.

Upgrade	Recommended Product	Price Range	Priority
Slide Milling for Optics	Jagerwerks / Maple Leaf Firearms / CHPWS	$100-$200	High (if you want a red dot)
Red Dot Optic	Trijicon RMR Type 2 / Holosun 507C X2	$250-$450	Optional (requires slide milling)
Trigger	Overwatch Precision TAC / Apex Action Enhancement	$75-$150	Recommended
Weapon Light	Streamlight TLR-7A / Surefire X300U	$120-$300	Essential for duty/HD
Extended Magazine	Glock OEM 19-round or 24-round	$25-$40	Optional (two 19-rd mags already included)
Holster	Safariland 6390RDS / T.Rex Arms Ragnarok / Tenicor Malus Sol	$50-$200	Essential
Grip Enhancement	Talon Grips (Pro or Granulate) / Stippling	$20-$25 (Talon) / $80-$150 (stipple)	Optional

Since the 19X already comes with night sights, your first upgrade dollar is better spent on a weapon light and a quality holster. The Streamlight TLR-7A is my go-to for a compact light that sits flush with the muzzle. If you want maximum output and are not concerned about size, the Surefire X300U is the duty standard. A trigger upgrade is the logical next step after that.

For holsters, the 19X shares holster compatibility with the Glock 45 and most Glock 17 Gen 5 holsters. Safariland’s 6390RDS series is the industry standard for duty use. For concealed carry (where the 19X is admittedly not the ideal choice), the Tenicor Malus Sol or T.Rex Arms Sidecar handle the longer grip well. You can find lights, holsters, and accessories at Palmetto State Armory, Brownells, or Guns.com.

Concealed Carry Considerations

Let me be direct. The Glock 19X is not an ideal concealed carry pistol. The full-size grip is 5.47 inches tall, which is the part of the gun most likely to print under a cover garment. A standard Glock 19 or even the Glock 43X will conceal significantly better for most body types.

That said, plenty of people carry full-size pistols every day. If you dress around the gun with an untucked button-down or a jacket, the 19X can disappear in an appendix holster. I carried it for two weeks in a T.Rex Arms Sidecar and managed fine at 6’0″ and 195 pounds, but I was constantly aware of the grip printing when I bent over or reached for something. For a dedicated carry Glock, there are simply better options. For a duty gun that you occasionally conceal, it can work.

Who Should Buy the Glock 19X in 2026?

The 19X occupies an interesting spot in 2026. The Glock 45 and Glock 45 MOS have taken over its market position for most practical purposes. The Sig M17 offers more features for similar money. The best full size 9mm handguns list has gotten longer and more competitive.

So who is this gun for? Shooters who want the specific combination of factory night sights, Coyote Tan finish, and the crossover grip concept. Law enforcement and military personnel who value the 19X’s proven duty heritage. Glock collectors who want the pistol that started the crossover trend. And anyone who picks one up, wraps their hand around that full-size grip, and just likes how it feels. Sometimes that is reason enough.

If you just want the crossover concept and do not care about color or night sights, buy the Glock 45. If you want the crossover concept with an optics cut, buy the Glock 45 MOS. If you want the original, with the military provenance and the Coyote Tan finish, the 19X is still a fantastic pistol that will outlast you.

The Verdict: 8.5/10

The Glock 19X is the gun that proved the crossover concept works. Compact slide for easier holstering. Full-size grip for superior shooting comfort and recoil control. 17+1 capacity standard, 19+1 with the included extended magazines. Factory night sights. And the kind of reliability that makes Glock the default choice for more law enforcement agencies than any other manufacturer in the country.

After 1,500 rounds of mixed ammunition with zero malfunctions, I have no complaints about how this gun runs. The GMB barrel shoots tighter groups than older Glock barrels. The nPVD finish is holding up well. The ergonomics are the best of any Glock I have shot, and I have shot most of them.

[IMAGE: Close-up of the Glock 19X Coyote Tan nPVD slide finish and night sights showing minimal wear after testing. Alt text: Glock 19X nPVD Coyote Tan slide and factory night sights close-up detail]

Where the 19X falls short is value. No optics cut in 2026 is a genuine problem, especially at a $675 MSRP. The Glock 45 does nearly everything the 19X does for less money, and the G45 MOS adds an optics cut on top of that. The lanyard loop is a vestige of the military trials that serves no civilian purpose. And the Coyote Tan finish, while durable and distinctive, is a love-it-or-hate-it proposition that limits your aesthetic options.

Final Score: 8.5/10

Best For: Duty use, home defense, and shooters who want the best grip-to-slide ratio in the Glock lineup. The 19X rewards people who prioritize shooting comfort over concealability. With factory night sights, three magazines, and Glock’s proven reliability, it remains a strong choice for anyone who can look past the lack of an optics cut and appreciates the Coyote Tan personality.

FAQ: Glock 19X

What is the difference between the Glock 19X and the Glock 45?

Both use the same crossover concept: a compact G19 slide on a full-size G17 frame. The Glock 45 comes in standard black, adds front slide serrations, removes the lanyard loop, and is available in an MOS (optics-ready) variant. The 19X comes in Coyote Tan, includes factory night sights, ships with 19-round extended magazines, and has the lanyard loop. The G45 typically costs $50 to $100 less at street price. For most buyers, the Glock 45 or G45 MOS is the better value. The 19X is the choice for shooters who want the Coyote color and factory night sights.

Is the Glock 19X good for concealed carry?

It can work, but it is not ideal. The full-size grip (5.47″ tall) is the hardest part to conceal and will print under fitted clothing. A standard Glock 19 or Glock 43X will conceal better for most people. If you dress around the gun with looser clothing or a jacket, the 19X can be carried concealed in a quality appendix or strong-side holster. For a dedicated CCW gun, there are better options.

Can you put a red dot on the Glock 19X?

Not from the factory. The 19X does not have a factory optics cut. To mount a red dot, you need to send the slide to a machine shop like Jagerwerks, Maple Leaf Firearms, or CHPWS for milling. This costs $100 to $200 and takes one to four weeks depending on the shop. If you know you want a red dot, the Glock 45 MOS or Glock 19 Gen 6 are better starting points.

What magazines does the Glock 19X use?

The 19X uses standard Glock 17 magazines (17-round) and Glock 19-round extended magazines. It also accepts Glock 24-round and 33-round extended magazines. It does not accept Glock 19 15-round magazines because they are too short for the full-size frame. Any aftermarket magazine made for the Glock 17 (Magpul PMAG GL9 17-round, ETS, etc.) will also work.

Is the Glock 19X still worth buying in 2026?

It depends on what you value. The Glock 45 and Glock 45 MOS have essentially replaced the 19X in Glock’s lineup for most practical purposes. They cost less and offer more features (front serrations, optics cut on MOS models). The 19X remains worth buying if you specifically want the Coyote Tan finish, factory night sights, and the included 19-round magazines. As a shooting platform, it is still one of the most comfortable and reliable Glocks ever made. It just faces stiffer internal competition than it did at launch.
