Master Review Sig P365: Reliability Stats, Accessories, and Mods

If you’re anything like me then you like to do a lot of research before you buy a new firearm, especially a carry gun. Instead of taking hours finding good videos and reviews, I’ve aggregated all the best information on the Sig Sauer P365, its reliability stats, and the best holsters, lights, mods, and more. Keep reading to see if this pistol is a good match for you.

Overview

The Sig Sauer P365 was released on January 8, 2018 and it caused quite a stir in the gun industry, mainly due to its crazy magazine capacity.

Up until that point Glock was ruling the market with their sub compact Glock 43, which was limited to a 6+1 in stock configuration where as the mighty P365 could carry up to 12+1 rounds of 9mm. Did I mention that the guns are almost exactly the same size?

See the image below for a size comparison between Sig and its competitors.

Some have said Sig made a voodoo pact with unknown and unknowable gods to cram that many rounds into such a small package. Ok, no one but me has brought that up, but I think it’s a valid point!

Never the less it is an impressive gun on paper. It’s even more so considering you can easily pick up a new one for under $500 bucks.

Sig P365 Specifications

Sig calls this pistol a “micro compact” and it’s easy to see why. It is fairly diminutive for such a capable gun. It is a striker fired semi auto, only available in 9mm. Check out the full stats below.

Like many popular self defense guns, the P365 uses a polymer frame and a steel slide. It has a very short barrel at only 3.1 inches which can make some guns this size hard to shoot accurately, but as we’ll see further down accuracy isn’t a problem for this little guy.

Sig Sauer P365 Accuracy

This micro compact might be the most accurate pistol in class. Concealed Carry reported off hand accuracy of 3 inches at 15 yards which is a very solid figure for a full size pistol, let alone a gun with a 3 inch barrel.

Most other reviewers will give this an 8 or 9 out of 10 for accuracy and nearly all reviewers remarked that it was much more accurate than it needed to be given the close ranges this pistol would be expected to be used.

Check out this video and you will see some great shooting from the P365 as well as tons of other great information.

Now it’s clear he is quite a skilled shooter, but this is still great for a micro compact pistol.

Reliability

This is the big elephant in the room. Sig has been known to produce some great guns that in the past have been released prior to all the kinks being worked out.

The first generation of the Sig Sauer P365 followed in that vein. Some shooters reported issues with failures to feed and extract some types of ammunition. They also reported other issues like primer drag which caused firing pins to bend or break.

Obviously this caused Sig to change the design of the pistol and tweak a few minor issues. The folks over on Sig Talk forum have a great thread on this, and it seems that P365 pistols manufactured after June 2018 are the best bets for those that want maximum reliability.

Sig P365 Reliability Statistics

Concealed Carry did a great review that was incredibly in depth early last year on the P365. They were working with the “first generation” of P365 prior to the striker redesign and this is what they had to say about the reliability.

“Overall, when shooting even just decent quality brass-cased loads, the P365 exhibited a 99.96% reliability rating.

I have spoken with numerous P365 owners, and I have personally witnessed several P365 owners fire their guns. Some of these were in handgun courses I instructed this year. I estimate that I have seen approximately an additional 5,000-6,000 rounds fired through about 10 other P365 pistols. While I have seen a few malfunctions occur, and some seemed to experience more malfunctions than I did including with brass-cased ammunition, I can still count the TOTAL number of malfunctions I have witnessed in all these other guns on less than two hands. Worst-case scenario, the P365 is still 99.85%+ reliable. This represents a little more than 1 malfunction every 1,000 rounds, I estimate about 1 in every 750.”

It seems from their statistics and others that this firearm is very reliable in terms of it’s mechanical function, but if you watch the Youtube video above you will note that there is one other issue that can cause failures to fire.

User Induced Reliability Errors

The reviewer in that video notes that on occasion, when he grips very hard, he activates the triangular shaped mag release with the palm of his off hand.

This is not a problem unique to this platform but, it can cause the magazine to drop slightly, which will keep the slide from stripping off the next round, giving you the dreaded click instead of a bang.

The only way around this will be trying the weapon for yourself using your own hands and grip. It may or may not be an issue for you.

Sig P365 Accessories, and Mods

We all know this is a carry gun, which means that we will need to accessorize it as my wife would say. The first thing that comes to mind is finding a good holster.

Sig P365 Holsters

There are ton’s of holsters depending on where you like to carry, but for the purposes of this article I will be discussing options for the three most popular methods of concealed carry: outside the waistband, inside the waste band, and appendix.

Inside the Waistband Appendix Sig P365 Holster

The Tulster Inside the Waistband Holster looks very solid, especially if you plan on carrying it with the Streamlight TLR 6, made for the P365. This particular holster allows you to wear it appendix carry or adjust the can’t so you can wear it anywhere from appendix to 6 o’clock.

You can choose ton’s of colors so it can match your outfit as well. You’ve got your regular black, carbon fiber weave, and other crazy colors. I’m a little partial to this multicam version myself. It says sure I’m cool, I might even be an operator.

Inside the Waistband Holster Sig p365

One of my favorite holsters for my carry gun is the CrossBreed SuperTuk. It’s the best way I’ve found to carry at the 5 o’clock position, and it hides your firearm very well.

This is an IWB holster that uses a leather backer to spread the pressure from the firearm. It is very comfortable for all day carry, including sitting in a variety of positions, and chairs.

Outside the Waistband Holster Sig P365

Carrying OWB is almost always the most comfortable option, and it generally is the fastest to access, but it tends to be less concealable. This holster from Outlaw Holsters looks pretty legit.

It fits standard 1.5 inch belts and has a pretty sweet subdued American Flag pattern on it. If you don’t like it then go back to Russia!

Now that we’ve covered the basics for a carry gun, let’s get into some of the fun stuff. The lights, lasers, and customizations for the Sig Sauer P365.

Lights, Lasers, and Red Dots P365

So far we’ve got your average Sig P365 carry gun, and holster. This rig is something a Karen, or a guy named Gary might carry, and we can’t have that. We need to look at customizing our particular carry gun for our intended use.

Lights

I highly recommend adding a carry light to a defensive firearm. It’s not a must have, but it can really help clarify some ambiguous situations. There are quite a few to choose from, but as I was doing the research for this article it seemed as if there were really two main contenders especially as it relates to finding holsters for the light gun combo.

The Sig Sauer Foxtrot Light

The Foxtrot 365 light is very cool. Because it was designed from the factory to integrate with the 365, it blends in tremendously well, leaving your with a streamlined package. Sig also manufactures holsters for this combo.

This light has two key features you need to know about. First it is a 100 lumen light with a 30min run time, which some might scoff at in our modern age of 1000 lumen defensive lights. Honestly, 100 lumen is perfect for a dark environments and it isn’t likely to blind you should you splash it off a light colored wall or reflective surface.

Secondly, it has a pressure activation switch which is a great feature. It allows you to activate it with the natural motion of squeezing the grip. The only down side here is that you have to really practice to activate correctly every time.

Streamlight TLR 6

The Streamlight TLR 6 packs a ton of features into a small package. It too is 100 lumens, but lasts 1 hour. Most importantly it also integrates an aiming laser with the light.

Generally I think an aiming laser can be over rated as most people don’t ever practice with it, but it can be a real life saver for those that have vision issues or want it for deterrent effects.

This device has several modes. You can use it as a light only, laser only, or combo. It is activated by your trigger finger or your off hand thumb depending on your grip. It does not have grip switch activation.

Red Dot Sights

This is where we start getting into turning our economical sig into a space gun from the future. Personally it’s kind of neat to have a red dot on your pistol, but if you don’t practice with it you are no better off and arguably worse off.

So far the Sig community seems to favor the RMSc as a the go to red dot sight for the Sig P365.

This little guy features a 4 moa dot that is completely parallax free. It has a three year battery life which is pretty nice. It also fits nicely on the very small P365.

Customizing the Sig p365

There are a few companies out there customizing p365’s and why not? You want to be able to find in a pile of guns quickly right?

Stippling

This is one of the more useful modification you can do to a carry gun. If you’ve never held a stippled gun you don’t know what you are missing. It feels like the grip is gripping you back. Or said more descriptively, it feels like pumice stone texture on your skin.

If you want to get your Sig P365 stippled, Battle Ready Arms will do it for just a few pieces of paper with dead presidents on them. Their work looks pretty good and from what I can see their prices are about what you would expect.

Flat Trigger

In the same vein, many folks prefer a flat trigger as compared to a curved trigger. Flat triggers can feel a little bit lighter due to increased leverage. This is very much personal preference and I recommend you try someone else’s trigger before buying your own.

Fabricated Arms Full Customization

If you really want to go hog wild then Fabricated Arms is the company for you. They can do almost anything your heart desires. They can cerakote your sig p365. They can mill the slide, and they can cut and install the RMSc. Check out their handiwork below.

This guns look totally sweet, and if you want to see more cool pics like these then give Chris a follow on Instagram.

The Final Verdict on the Sig P365

This has been a long, detailed post, but the final question remains. Is the Sig P365 a good carry gun? I think the answer to that is yes. It has very good reliability especially those pistols made in the last year or so.

It’s broadly supported in the after market so you can set it how you want, depending on your personal use case. It also has the best magazine capacity available and is more than adequate for self defense situations.

If it were me I would probably buy a 365 and ship it off to Fabricated Arms for a multicam black cerakote, and stipple job. I’d probably carry the 12 round extended magazine and I’d go with the Crossbreed holster, but that’s me.

Turn yours into a space gun or leave it bone stock. Either way carry where you can, and practice with what you carry!
