The Sig Sauer P320 AXG-Legion offers an excellent shooting platform in a good-looking package.
The most recent iteration of the storied Sig P320 comes as part of the gunmaker’s fantastic Legion series. It is the P320 AXG-Legion chambered in 9mm Luger, an all-metal pistol that will make decent shooters good and good shooters great. I know this is a bold statement, but it is difficult for me to imagine anyone who gives the pistol a try disagreeing.
My first experience with the Sig P320 came on a beautiful Texas spring day at the same Mad Max shooting range used by Colion Noir in most of his gun review videos. I was all alone and walking down “The Street,” blasting steel poppers and testing a new high-pressure ammunition in my carry guns.
Shooting the Sig Sauer P320 AXG-Legion
Once I finished, I opened the case to the AXG-Legion and began to load standard range ammo into all three of the 21-round metal magazines that come with the gun.
Yes! Each magazine holds a stunning 21 rounds, making the pistol a 22-round badass. The mags do protrude about .65 inches from the bottom of the flared magazine well but looks fine due to the textured shrouds around the base of each magazine. It was time to have 64 rounds of fun!
The AXG-Legion feature that initially caught my attention was what Sig termed the “two-port slide integrated expansion chamber.” Sig claimed that felt recoil was mitigated by as much as 25 percent due to the two-port design. I was skeptical—until I fired two quick shots at the first popper. Though I thought I had heard two “tings,” I immediately unloaded the gun, locked the slide back, and examined the barrel. I wasn’t sure I had actually fired a second shot and checked to see if I had a squib load, with a bullet stuck in the barrel.
Going from the higher-pressure ammo to a standard velocity range load was part of why I thought I might have had a squib load. But I did not. Two shots, two hits. The ports did their job and better than I ever would have imagined.
The next-to-no muzzle rise allowed me to double-tap 20-yard steel as I walked through the range. Sig sent the pistol with its Romeo1 Pro wide-window optic mounted on the pistol’s optics cut slide. A red dot usually exaggerates the perception of muzzle rise, but I still sensed little to no rise.
Sig Sauer P320 AXG-Legion: Features
While a full-sized pistol, the Sig Sauer P320 AXG-Legion is not too big to carry concealed even for a shorter, thinner guy like me. I carried it for a couple of days in my favorite PHLSTER Pro appendix holster. The standard P320 17-round magazines are not compatible with the AXG-Legion’s aluminum magwell. But Sig does sell flush 17-round magazines for the AXG. If I were to carry it regularly, I would use one of these in the gun with two of the 21-rounders as spares.
The AXG-Legion’s flared magwell made speed reloads almost impossible to flub. It was like the gun was magnetically pulling the magazine into the well.
The flat skeletonized trigger felt perfect on my finger. It made me wonder where flat triggers were for most of my life. Sig has cracked the code on producing exceptionally smooth triggers with short, crisp reset in factory guns. The texture of the custom Hogue G10 grip panels and back strap, along with the checkering on the front strap, helped lock the gun in place. It also kept my red dot on target during fast strings of fire.
Other features that make this pistol so good? Count on the beefy, push-button magazine release, extended beavertail, aggressive front and back slide serrations, and tritium three-dot night sights with the larger front sight dot to bring your attention right there.
Then, there is the nicely done Legion gray Cerakote finish on the frame and slide, along with the Legion logo subtly cut into the grips. These aesthetic features will not help you shoot any better, but they will certainly make you feel better.
All these features and functionality make the AXG-Legion a great-looking package that truly performs.
