The Sig Sauer P365 Nitron is a legend in its own lifetime. So there was always going to be a slew of Sig P365 accessories, upgrades and aftermarket parts.
Sig P365 SAS Might Be Best Custom Sig Nitron
Sig Sauer has even sent its own engineers to work to refine the new benchmark for concealed carry pistols. The Sig Sauer P365 SAS is the result and it costs just $599.99.
Sig P365 SAS is a Great Custom Gun
Before you go spending $1000 to tune a stock Sig Sauer P365 Nitron, make sure this wasn’t the custom Sig you wanted all along.
It has a ported slide. You also get a trick Meprolight FT front sight that works like a very vague red dot.
It’s not as accurate at the range as classic sights that line up planes. But as a defensive sight then we like it a lot. Especially integrated into the slide like this.
That’s a long way towards a completely custom gun and you no longer have to buy
Or Just Buy a Custom Gun

But if you want a DIY custom gun, what are the best Sig Sauer P365 accessories for sale in 2019? Here are our picks.
1. Grayguns Grip Module Sig P365
- Price: $84.99
Halle Berry carries a full custom Grayguns Sig P365 into battle in John Wick 3.
You can get the
Grip modules are seriously good these days and you have to switch out the internals. That’s it. You don’t have to register a new frame with grip modules, it’s kind of a jacket for your existing gun.
Custom stippling is harder than it looks, too, and this Sig P365 grip module is pre-cut to perfection. A few minutes with the gunsmithing tools and you’re good to go. And let’s face it, there’s no way you could achieve this look with a hot iron.
This also works if you did stipple your gun and got it horribly, horribly wrong.
2. Sig P365 Extended Magazine 15 Rounds
- Price: $39.99
Sometimes the cheapest and simplest mods you make are the best. And there is no denying the straight value of a five extra rounds in each mag.
An extended mag is one of the fastest ways to measurably improve any gun. This one isn’t the prettiest, but it does give you some extra real estate to get a better grip on your gun.
The benefits go beyond the extra ammo, but that’s really the big news here. Five more rounds between rounds makes the rest of this stuff look like window dressing.
3. Custom Slide For Sig P365
- Danger Close Armament Signature Slide Sig P365
- Price: $699.99
Custom slides for the Sig P365 accessories market are big business. But not all the big guns have options out yet.
So there has been a gold-rush of minor and no name outfits producing P365 slides. But the only Sig P365 accessories our partners will sell you is the Danger Close Armament Sig Sauer P365 Signature Slide.
This 3 inch slide is an eye-popping $699.99, but it is ported, fitted with night sights and finished in black Cerakote.
4. True Precision Threaded Barrel
- Price: $170.99
A
The threaded barrel is good to go with a 9mm
This custom Sig P365 barrel is made from 416R steel. A match-grade barrel gets 6-groove rifling. The SAAMI spec chamber and polished feed ramp should give you a tangible improvement with the cycling times too.
If you have opted for a ported slide, too, then this barrel will peak through and transform the look of your custom pistol.
True Precision is already well known in the Glock modding community for its match-grade barrels and the occasional custom slide. It tends to focus on the shorter Glock 43, and models like the Smith & Wesson M&P Shield.
5. Sig Sauer P365 Flat Trigger
- Price: $44.99
The flat trigger that comes as standard on the Sig P365 XL just looks better.
Does it feel better? That’s much more subjective. But the aesthetic argument is just done.
Well you can throw away your traditional trigger and replace it with a 365 upgrade that is an OEM part from Sig.
Just $45 at the Sig parts & accessories store at Rainier Arms will get you the real deal and it’s a cinch to fit.
6. Sig Sauer Foxtrot365 Tactical Light
- Price: $149.99
Things generally go bump in the night. So if you use your P365 as a nightstand pistol, or you’re happy to compromise concealment for capability, then this can be a real benefit.
At night, a blinding light can be all you need to gain a competitive advantage. This 100 Lumens LED light is seriously powerful.
You get a hand free that would otherwise be full of flashlight and your weapon follows your light which follows your eyes. There are serious tactical advantages to a weapons light.
Obviously, the Sig Sauer Foxtrot360 Tactical Light does advertise your position pretty clearly. In most one on one situations, though, that’s not a concern.
You can remove the light with a single wrench in seconds for daytime use or better ease of concealment. When you need to shed some light on things, though, you’ll be glad you have the Sig Sauer Foxtrot365.
7. Crossbreed Supertuck IWB P365 Holster
- Price: $55.80
Crossbreed Holsters are some of the best Sig Sauer P365 holsters on the market.
The Crossbreed
8. Reflex Mini Red Dot Sight
- Price: $400
Not everybody wants a reflex sight on their concealed carry pistol, until they try one.
Plenty of people don’t have 20/20 vision anymore. In a personal defense situation, too, nerves go through the roof and focus can be a real issue. It isn’t a sin to take all the help you can get.
Micro red dots are taking off in a big way and we can vouch for the Shield. It automatically adjusts to the brightness and gives you a clear field of view through the reticle.
That in itself can be huge, although it is limited in what it can do with the dark.
If you are going to spend that kind of money on an optic, you might want to go the whole hog and buy this custom gun from Danger Close Armament.
It comes with the optic as part of an extensive package of goodies that add up to good value. Even at $1,699.99…
9. Sig Sauer SRD9 Suppressor
- Price: $699.99
- Caliber: 9mm
Some States still want you to have fun and a suppressor can be just that. But where can you buy a suppressor for the Sig P365?
We got you.
Now forget about barrel length, weight, everything. But you knew that right? And your gun might not cycle, maybe 50% of the time. But except for that…
You do get this in return though…
Your 9mm silencer should play nice with most threaded barrels in this caliber and you could even find yourself strapping it to a 9mm AR pistol or
A suppressor and the NFA paperwork that goes with it can be a real investment.
Your Sig Sauer P365 will look ridiculous and might not cycle too well with this monster up front. But try it, for a laugh.
You know you will.
10. Sig Sauer Lima P365 Laser Sight
- $149.99
This OEM laser sight slots right on to the Sig Sauer P365 Nitron for a low-drag draw that paints a red dot right on the target.
In the heat of the moment, a clear line of fire can be a lifesaver. The light alone has that intimidation factor, too, so some people prefer to carry a weapon-mounted laser sight.
This one is a Sig Sauer part so it’s designed to fit like a sleek glove. It attaches to the rail and simply slots on and off, but it’s designed to shrinkwrap itself to the frame.
Automatic battery shutoff means the laser only lights up the sky when you point it there. Apart from that, there’s not much to say. This is the best laser for the Sig Sauer P365.
9. Tyrant Designs Sig P365 Compensator
- Price: $75.95
Call it the John Wick effect, but we’re all that little more accepting of compensators on small guns thanks to the super assassin.
You know it’s true.
You also know that the Sig Sauer P365 Nitron, while awesome, is a little snappy. Tyrant Designs claims to have tamed the beast with this simple Sig P365 compensator.
You’ll need a threaded barrel, but the compensator screws right on and you can use any open ended holster with this compensator attached.
But if you have the 365 and you just want to calm the muzzle rise, then this is the Sig P365 accessories you need.
Here’s the Tyrant Designs T-Comp in action on a Glock 19 and we have to say, it looks like it’s working.
