It’s crazy that a few years ago, SIG introduced the p365 and changed the firearm industry.
This gun almost single handily killed two genres of compact firearms, the single stack 9mm and the subcompact. The little gun was the size of a single stack 9mm but held the same amount of rounds as a subcompact pistol. Since then, the P365 has evolved into an entire family of guns, and today, we are going to break down each model, its specs, and where they work best.
P365
Barrel Length – 3.1 inches
Overall Length – 5.8 inches
Width – 1 inch
Height – 4.3 inches
Weight – 17.8 ounces
The original P365 is still the most popular. This micro-compact 9mm offers you ten rounds of 9mm in a flush-fitting magazine, and the entire gun is the same size as contemporary single-stack 9mm guns. The key to its success was the hybrid double and single-stack magazine design. This made it thin but kept capacity at ten rounds minimum.
This weapon is fairly simple, fairly standard firearm with an included set of night sights. It’s plain but sized right for nearly any method of concealed carry. The P365 is also the most commonly available model and often the most affordable. It’s an excellent all-around option for concealed carry.
P365-380
Barrel Length – 3.1 inches
Overall Length – 5.8 inches
Width – 1 inch
Height – 4.3 inches
Weight – 17.8 ounces
SIG took the standard 9mm P365 and converted it to the slightly shorted cased .380 ACP cartridge. They didn’t do much for the conversion, and it’s the same size as the 9mm. Heck, the magazines are basically the same size, except the .380 ACP magazines are shimmed for the 17mm long cartridge. The big difference is that the P365-380 is optics ready.
The big benefit was creating a gun with much less recoil. The little .380 ACP round is much softer shooting, especially in the P365. It’s one of the comfiest guns to shoot and is perfect for someone with compromised hand strength.
P365XL
Barrel Length – 3.7 inches
Overall Length – 6.6 inches
Width – 1.1 inches
Height – 4.8 inches
Weight – 20.7 ounces
SIG saw an opportunity to go bigger with the P365 and took it. The XL stands for extra large in this case, and the increased size all around. This includes a longer grip and barrel. The longer grip also means the 10-round magazines are a no-go. The flush fitting magazines for this gun are 12 rounders(Ten-round magazines are produced for ban states but are 12-round length.)
Accommodating the P365XL was also the release of a 15-round P365 magazine as well. The P365XL also accommodates optics with the shield footprint. This tiny gun could be made very modern, very quickly. For those looking for something a little bigger than the P365, the XL fits the bill.
P365X
Barrel Length – 3.1 inches
Overall Length – 6 inches
Width – 1.1 inches
Height – 4.8 inches
Weight – 17.8 ounces
The P365X model is the standard P365 slide on top of the P365XL grip module. This creates a slightly longer grip while retaining the shorter barrel length. Additionally, SIG included an optics mount with the P365X pistol.
This creates a P365 variant that is very comfortable. The longer grip makes it easier to shoot and hold onto, and the shorter slide makes it lighter and comfier for carry. It’s very much the central A/C of the P365 series. It’s a great compromise and embraces optic enhancement.
P365 SAS
Barrel Length – 3.1 inches
Overall Length – 5.8 inches
Width – 1 inch
Height – 4.1 inches
Weight – 17.8 ounces
The SAS model is a niche variant of the standard P365. SAS stands for SIG Anti Snag, and this is a process SIG has long used to make a firearm more appropriate for deep carry. They melt corners and trim anything that can snag off of the gun. This includes the sights. There is no front sight, and the rear sight sits flush with the slide. This three-dot read sight is odd to use but effective with training.
The SAS also has a flush-fitting takedown and slide catch lever.s It’s a smooth criminal designed to be carried as deep as possible, almost like a modern ASP. SIG made an interesting choice in porting the barrel to help reduce muzzle rise. This is the only protected P365.
P365 XMacro
Barrel Length – 3.1 inches
Overall Length – 6.6 inches
Width – 1.1 inches
Height – 5.2 inches
Weight – 21.5 ounces
The XMacro is the newest variant of the P365, and it’s also the target. It’s aimed to dominate the Glock 19-sized pistol market. It still has a 3.1-inch barrel, but an integrated two-port compensator makes it the same length as the P365XL. The grip is a fair bit longer, and the XMacro comes with a 17-round magazine.
On top of that, the gun is cut and ready for optics and comes with a standard Picatinny rail. It’s a much bigger gun but still fairly compact and easy to carry concealed. The little gun is ultra-easy to shoot and delivers a very soft shooting experience.
P365XL Spectre
Barrel Length – 3.7 inches
Overall Length – 6.6 inches
Width – 1.1 inches
Height – 4.8 inches
Weight – 20.7 ounces
The P365XL Spectre is SIG’s first Custom Works edition of the P365. It’s the same in capability as the P365 but possesses a much fancier finish and some custom slide work. Later models have skeletonized triggers and gold-colored barrels.
P365XL Spectre Comp
Barrel Length – 3.1 inches
Overall Length – 6.6 inches
Width – 1.1 inches
Height – 4.8 inches
Weight – 20.7 ounces
The P365XL Spectre Comp is another Custom Works P365 and another XL model but with a slight shift. The barrel is only 3.1 inches long, but an integrated compensator makes it the same length as the standard P365XL. It retains the gold-colored barrel but ditches the flat, skeletonized trigger.
All the SIGs
So far, as of this writing, this is all the P365s currently on the market. I have no doubts that SIG will continue to evolve the platform. What’s next is hard to say. Personally, I’d love to see a .22LR version for training purposes. Maybe it will evolve to chamber .30 Super Carry. Only time will tell. The only thing we know for sure is that the SIG P365 will continue to be an innovative firearm.

I’ve owned a SIG P365 since 2018, and I’ve been very pleased with my choice. Bought because I could no longer make out the sights on my PPK/S in Low Light Drills. The SIG’s Night Sights just popped for my old eyes. I carry it with a 10 round Mag, but keep two 12 rounders in my EDC set up. With the 12 round Mags, it is easier to hold on to, but it prints with a 12 round in the gun on me.
Loaded with Hornady 135 gr +P Critical Duty, it functions smoothly and checks all the boxes. I highly recommend the SIG P365, in whatever configuration meets your needs.
I would love to see SigSauer come out with a P365X chambered for .22 LR. I have a P365 SAS, but couldn’t get use to the sight. I bought a P365X slide with red dot sight mounted and now Love the little gun. It is Killer!
