Sig Sauer P365 AXG Legion Review: Everyday Carry Perfection?

What do you do when you already make the number one selling handgun in the US? You make it even better.

Or at least that is what Sig Sauer set out to do. They have billed their P365 AXG Legion as the “perfection of a carry pistol.”

So, is this upgraded version really the best-in-class? Or is it just another SKU in an already mind-bogglingly huge lineup of P365 pistols?

We got our hands on one of the newer P365 AXG Legions to find out for ourselves. Join us as we go over the results of our testing below!

Sig P365 AXG Legion Backstory

While Sig didn’t invent the concept of a 1-inch-wide micro-compact pistol that holds 10+ rounds (that distinction goes to KelTec), they revolutionized the genre with the introduction of the P365 in 2018.

In 2022, Sig released the P365 X-Macro Comp. The Macro brought a full-size 17-round magazine capacity into a gun that was shorter and thinner than a Glock 19.  

With hopes of improving the shooting experience even more, Sig released a metal-framed version of the X-Macro Comp a little over a year later — the P365 AXG Legion.

Shooting the Sig P365 AXG Legion: Accuracy & Reliability Analysis

The standard X-Macro Comp was already considered by many to be the “ultimate do-all gun.” It is thin, high-capacity, relatively easy to conceal, and shoots well thanks to its ported slide.

So, how do you improve the design? Add weight to make it softer shooting. The original polymer X-Macro Comp comes in at 21.5 ounces, while the 365 AXG Legion weighs 26 ounces.

While 4.5 ounces might not sound like a huge difference, it is a 21% weight increase.

The gun is probably the flattest-shooting gun of its size, but how much of that is due to the weight is tough to say.

In addition to the ported slide it shares with the regular X-Macro, it also offers improved ergonomics that heavily factor into how well it handles.

Accuracy

Despite having a lackluster trigger (more on that in a bit), the accuracy of the P365 AXG Legion in both slow fire and at speed is pretty darn good.

I ran a Sig ROMEO-X Enclosed Compact optic for the entire duration of testing.

Doing some standing slow fire at 7 yards revealed that I could get 5-shot groups with all the rounds touching on most types of ammo I tested.

The only ammo that didn't produce the accuracy I expected was the AAC 115-grain FMJ. I highly suspect this may be a sub-par batch, as it has caused accuracy issues with a few other firearms as well.

Where this gun really shines is in defensive shooting drills. Whether I was running Bill Drills, Mozambique drills, or just outright mag dumps, the Legion made it easy.

There is a bit of snap to the recoil, but you don’t feel it as much because this gun cycles very fast due to the low slide mass and ported barrel. It snaps right back to zero for me with little effort.

Reliability

Over the course of 500 rounds, I had zero malfunctions. It ran flat-nose FMJ, round-nose FMJ, and various types of hollow points without issue.

We have also tested an earlier version of the same gun a few years back, which was also issue-free.

Ergonomics: Fit & Feel

I love metal-framed guns, and I know I am not the only one.

While the regular X-Macro Comp feels good in my hand, the AXG Legion takes it to a new level.

You get some medium-aggressive G10 grip panels, front and backstrap checkering, a generous trigger guard undercut, and even some checkering on the bottom of the trigger guard itself.

All of that is capped off with a metal removable flared magwell that helps keep my support hand tucked nicely on the grip.

Simply put, the grip feels great to me. It is slim, superbly contoured, and the metal frame gives it a solid hand feel.

The slide release and mag release are both easy for me to reach and actuate without breaking my shooting grip, but neither gets in the way during shooting.

A full 1913 Picatinny makes it easy to mount accessories, like the TLR-7 X pictured below.

Sights & Optics

Sig offers the P365 AXG Legion with either the common Shield RMSc mounting footprint or the improved SIG-LOC footprint for use with SIG-LOC optics.

They tout SIG-LOC as being a stronger mounting system due to its design, which features five points of contact. I opted to give it a try and had absolutely no problems with the optic holding zero or coming loose.

The ROMEO-X Enclosed Compact I used has a low enough deck height that it gives a lower 1/3 co-witness with the standard-height irons.

While the SIG-LOC footprint seems nice, if you aren’t keen on running a Sig optic, I’d just opt for the standard RMSc footprint.

For anyone not interested in running an optic, you get Sig’s standard XRAY3 3-dot tritium night sights. I always find these sights to be simple and effective.

Trigger

Unfortunately, the trigger is the Achilles’ heel of this gun.

I own and have shot several P365 variants, and no two triggers ever truly feel the same. Sometimes you get a decent one, and other times, not so much.

Using a Birchwood-Casey mechanical trigger gauge, this specific P365 AXG Legion had a five-pull average trigger weight of 5.2 pounds.

However, the weight really isn’t the issue here. The pull is spongy, then there is a spot with some notable grip, then it gets spongy again before breaking in space.

It is a grab bag of textures that ends with an unsatisfying thonk. The reset is good, though, being fairly short and both audible and tactile.

But as I stated earlier, the trigger oddly didn’t hinder me in either my accuracy testing or speed shooting. It is not bad to the point of affecting how the gun shoots; it just feels…blegh.

Gen 1 vs. Gen 2

It should be noted that in early 2025, Sig stealth released a slightly revised Gen 2 version of the P365 AXG Legion.

The only differences were a wider trigger guard, different rail dimensions, and some improvements with the slide-to-frame fitment.

This is only important to the end user when it comes to holster fitment. Most older P365 AXG Legion holsters that fit Gen 1 guns will not fit Gen 2 guns. Be sure to triple-check with the holster manufacturer before buying.

Improvements We’d Like To See

My only major point of contention with this gun is the trigger. If Sig managed to get an improved trigger with a cleaner feel and a crisper break, this gun would be nigh-unbeatable.

If I had to nitpick for one more improvement, it would be to make the front and backstrap checkering extend a bit further vertically for even more grip control.

Who Is It For?

The P365 AXG Legion rides that fine line between an everyday carry gun and a true duty pistol. It is thin enough to be easily concealed, but still has the capacity and shootability of a full-size pistol.

Its metal frame makes it geared toward people seeking a more premium feel and refined shooting experience.

But that premium feel comes at a price. With the P365 AXG Legion coming in around $1,299, it is about $450-500 more than the standard P365 X-Macro Comp.

While I feel that the standard X-Macro gets you about 90% of the same shooting experience, I cannot deny how much better I like the way the P365 AXG Legion feels in my hand. Only you can determine whether it is worth the price difference.

By the Numbers

Reliability: 10/10

I had zero stoppages during the entire course of testing. Whether it was flat-nose, round-nose, or hollow points, it ate it all. It worked great even with fully loaded mags and one in the chamber.

Ergonomics: 9/10

The metal frame, G10 grips, and general control layout make this the most comfortable micro-compact framed gun I have ever shot.

Accuracy: 7/10

For a 3.1-inch barrel, the accuracy is pretty impressive. It is also easy to be accurate when shooting fast, thanks to its fast cycle time and ported slide. I am knocking a few points off for the sub-optimal trigger, even though it didn't heavily affect the overall shootability.

Customization: 10/10

With the Sig P365 series being the best-selling handgun in the US and its modular Fire Control Unit, the aftermarket is nearly unlimited.

Value: 6/10

While the gun does feel nice, paying around $500 just to get a metal frame and a few other minor improvements will be tough to justify for some folks.

Overall: 8/10

How We Tested the Sig P365 AXG Legion

I tested the Sig P365 AXG Legion with 500 rounds of the following ammo:

• Winchester Target & Practice 115 gr flat-nose FMJ - 150 rds
• Magtech 115 gr FMJ - 100 rds
• AAC 115 gr FMJ - 50 rds
• Speer Lawman 124 gr TMJ - 100 rds
• Sig Sauer Elite Defensive 115 gr V-Crown JHP - 50 rds
• Speer Gold Dot 124 gr JHP - 50 rds

Accuracy testing was conducted freehand at 7, 10, 15, and 25 yards using B-27 targets. To gauge the gun under recoil, I did various drills, including Bill Drills, Failure-to-Stop drills, double-taps, and emergency fast mag dumps.

I applied a small amount of lube to the frame and slide rails once at the 300-round mark. Reliability was assessed by the total overall performance of the pistol during the 500-round count.

Final Verdict on the Sig Sauer P365 AXG Legion

The Sig P365 AXG Legion proved to be a reliable, accurate handgun that packs a ton of rounds in an extremely thin and concealable form factor.

So is it the perfect everyday carry pistol? For me, the answer is no, but it'd be pretty darn close if it had a better trigger.

But I have no doubt that for some of you, this will absolutely be the Goldilocks gun you are looking for, provided you can stomach the price.
