Sig Sauer P365: Will It Trip Your Trigger?

As often happens, I’m late to the game. I know, I know, you’re shaking your head out there. Why did I wait so long? Because the first couple of times I checked the Sig Sauer P365 out, the grip just didn’t do it for me. I thought it was too small in proportion to the rest of the gun, and frankly, I thought it felt stupid. Well, guess who was the stupid one? More on that shortly.

Everyone I talked with seemed to be fawning over the P365, and it struck me as a gun that all the “cool kids” simply had to have. Like an exclusive club or something. I got sick of hearing everyone rave about it. Life goes on, and things are hectic, so I never got around to getting a P365.

After the fourth or fifth time picking the gun up (this is in a span of a few years), I hefted the pistol recently, and it didn’t feel so stupid. Was I getting accustomed to the grip? I figured, “What the hell? I have very little to lose by buying one and seeing how it shoots,” so I bought the pistol. The real proof, I told myself, would come at the range. And with all the hype that friends were giving this pistol, it had damn well better be something extraordinary!

What does the Sig Sauer P365 bring to the table as far as specifications are concerned? Let’s take a gander.

Tech Specs

Introduced in 2018, this is a 9mm pistol (also available in .380 ACP) that weighs 17.8 ounces. It is 4.3 inches high and 5.8 inches long, with a thickness of one inch. The barrel length is 3.1 inches. According to Sig Sauer, it is rated for +P ammunition.

The slide is stainless steel with a black Nitron finish, so rust will not be an issue with this pistol. All the edges of the slide are beveled, which helps when holstering the pistol and prevents snagging. There are both forward and rear serrations on the slide, and they’re effective, offering a good purchase for racking the slide.

This pistol does not have an external safety installed, though one is an option for those who want one. The frame is polymer.

This pistol is optics-ready and is specifically designed to accept the ROMEOZero Elite red dot sight. Initially, optics-ready wasn’t an option among the early generations of the P365, but now they all come optics-ready.

It comes standard with two 10-round magazines—one with a flush-fit floor plate and the other with a pinky extension. I much prefer the one with the extension. I’ll discuss the magazine options shortly.

The cost is very competitive with the other micro-9s in this category; at my local gun shop, it set me back $495.

Magazines

Two 10-round magazines are shipped with the pistol, one with a flush-fit floor plate and the other with an extension so the shooter’s little finger has a landing zone. The flush floor plate magazine without the finger extension leaves my little finger dangling in space, which I don’t care for.

I immediately bought an optional 12-round magazine, which extends the grip slightly, making it very easy to get a solid, comfortable purchase on the Sig Sauer P365. That little bit of grip extension gives support to the rear of the pistol’s grip, which feels better in the palm of the shooter’s hand, and also gives additional leverage, which helps to control the pistol better during recoil. Overall, I love the 12-round magazine; it’s the sweet spot for this pistol, and I plan to get more.

Additional options include 15- and 17-round magazines, making this a truly versatile pistol. Being able to bring this little pistol’s capacity up to that of a Glock 19 or 17 is truly attractive.

Sights

Sig calls the sights XRAY3 Day/Night sights, and they consist of three dots that contain tritium. The front sight has a large, green circle that helps it to be visible to shooters in bright light. In low light, the tritium does what tritium does, which is to glow (in this case, green). Overall, the sights are decent. In my opinion, they’re nothing to get excited over, but they do their job well.

The rear sight has serrations on the back facing the shooter to cut down on glare. The rear dots are small and don’t draw attention to themselves; rather, the front sight is the star of the show, and this works out well. Those rear dots are there but not obtrusive.

Both the front and rear sights are metal, which is excellent (take note, Glock!).

Handling

The P365 handles like a dream. The bore axis is very low, which mitigates a lot of the recoil. It points naturally; as soon as the pistol comes up, it’s on target. The proportions of the pistol lend themselves perfectly to the hand, and it also conceals extremely well. Even with the 12-round magazine, it’s no problem to conceal at all.

When accessing the pistol from an IWB holster, it is not difficult to grip at speed.

Grip

I’m perplexed how they got the grip so small. Which is really to say, how in the world did they make the magazines so slim?! Sig’s engineers must have worked overtime on this project, and it was their first priority when designing the Sig Sauer P365.

The grip has stippling all around and is fairly rough, which gives it an excellent purchase. That said, it’s not obnoxiously rough, so it doesn’t tend to shred clothing when it comes into contact. Sig hit a nice balance with this texture.

There is an undercut at the trigger guard, so shooters can get a nice, high grip with their hand. The grip is slim, so those with huge bear paws for their hands might find an issue with that.

Some small pistols are a compromise, but this one isn’t. You can run this gun in rapid fire and expect the same accuracy that you’d get from a duty-sized pistol (even better, in some instances).

Trigger

Typical of striker-fired triggers, the P365 has a long, smooth take-up. When the wall is hit, there is some creep before the trigger breaks. It’s not a crisp release, it’s more gradual. To be honest, the trigger doesn’t excite me much, it’s not that great. Understand, I love the pistol, and the trigger is just “okay” in my book. This particular pistol wears a curved trigger.

Frame

Although the frame is polymer, there is a stainless steel fire control unit that fits into it, and this is the part of the gun that has the serial number. Because of this, the serialized unit can be placed into other grip modules, making the P365 highly customizable.

Controls

All controls are simple, including the takedown lever, slide lock lever, and magazine release. All work as expected, which is to say efficiently. Magazines eject positively. The slide stop is one of the better ones on the market in that it’s small and unobtrusive, but it protrudes enough that it’s easy to operate.

I will say that when I have a firm grip on the pistol and eject a magazine, my palm tends to put pressure on and hold the rear of the magazine in the magazine well. This is due to the short grip. I have to either shift my grip so the mag can eject or grab the magazine with my support hand to pull it out. It’s not a huge deal, but something that I’m going to need to work with. It’s not the fault of the gun, it’s a training issue.

Accuracy

The first time I shot the P365, I was pleasantly shocked by the accuracy that I was able to obtain. The group was about 2 1/2 inches, excluding a flier, at ten yards. That’s not very remarkable, but the speed at which I was shooting made the group remarkable; the pace was fairly rapid, and I did not expect the group to be so tight. This is one accurate pistol!

At The Range

I’ve already raved about the accuracy. As far as the muzzle flip is concerned, this is a micro-9, obviously, so there’s some muzzle flip. However, I will say that it is less pronounced than on most other small 9mm pistols. Again, the Sig engineers were dialed in when they addressed this issue. Follow-up shots with the P365 were rapid without difficulty.

As expected, reliability was 100% with several brands of ammunition, including Nosler’s ASP (Assured Stopping Power). A quick word about this hollow point ammo: It’s great stuff! Clean shooting and accurate, I currently have this ammo in the P365’s magazines as my defensive carry ammo.

In Summary

These days, the Sig Sauer P365 has pretty much become the yardstick by which all other micro-9mm pistols are judged. The very compact size, coupled with its excellent accuracy, truly brings a lot to the table. A pistol this small has no business being as accurate and controllable as it is. When I fire it, I marvel at how they managed to do it.

The small size, coupled with its excellent handling characteristics, makes it no wonder that this pistol has been the benchmark to which all other micro-9s are compared.

For some people, it could be a pocket pistol, but I consider it slightly large to fit in a pants pocket. Perhaps a coat pocket with a proper pocket holster would be more appropriate. Aside from that, it makes a superb concealed carry piece, and I carry mine in a DeSantis holster.

In full disclosure, I bought this pistol privately at a local gun shop. Sig did not help me out in any way for this article.

For the price, I don’t see how any manufacturer can beat the P365. Sure, you can find a cheaper pistol, but it is not going to be this good. I’m just sorry I waited so long to discover it.
