The heavy aluminum alloy frame with TXG tungsten-infused G10 grips provides exceptional weight, balance, and control. The stainless steel slide features an integrated expansion chamber for gas redirection and recoil reduction. Fit and finish are competition-grade—tight tolerances, smooth operation, and flawless cycling—backed by SIG’s reputation and strong user reports of reliability in high-round and competition use.
Handguard & Modularity — Standout Feature
The slide-integrated expansion chamber vents gas upward to dramatically reduce muzzle rise without added length or reliability concerns. Full ambidextrous controls (thumb safety, mag release) and flared magwell speed reloads; adjustable AX3 trigger allows customization. Optics-ready RMR footprint supports popular red dots with co-witness. Three 20-round magazines included; Legion program adds exclusive perks. Vast SIG aftermarket and 226 compatibility enable upgrades for competition or duty builds.
Accuracy & Performance
The 4.4-inch barrel with expansion chamber delivers outstanding accuracy—consistent 1–2 inch groups at 25 yards. The heavy frame and recoil mitigation make it exceptionally flat and soft-shooting; AX3 trigger (~3–4 lb) enables precise, rapid shots. Performance is elite—flawless cycling across 9mm loads (FMJ, JHP, +P), fast follow-ups, and competition-proven consistency across thousands of rounds.
Installation & Real-World Durability
Ready out of the box—mount optic, zero, and shoot. Durability is premium: aluminum/TXG frame and stainless slide withstand high-round abuse, recoil, and harsh conditions. Proven P226 heritage ensures reliability—minimal maintenance required for competition or tactical use.

Full Video Transcript – SIG P226 Legion X5 Review
0:00 Hey everybody, welcome back to the Armed Scotsman. Today on the table we have a SIG P226 Legion X5. I’m excited about this one.
1:08 Alright folks, as I said, this is the SIG P226 Legion X5. I’m down at Ready Gunner in Orem, Utah today. Thank you to them for having me here.
1:40 Let’s change the camera angle around, put this down on the table and go over its features.
1:48 One of the first things you’ll notice when you pick it up is that it’s a little weighty. This one has a solid steel frame instead of the alloy on the original Legion, coming in at about 44 oz unloaded.
2:01 It comes with three metal mags — I believe these are Mec-Gar. Excellent mags. These are 20-rounders.
2:16 Starting at the bottom: You’ve got a flared magwell that makes inserting mags very easy. They left the front open so you can still rip the mag out easily if needed — smart design.
2:55 The grips are G10 with the Legion logo on both sides. Very nice texturing all the way around and checkering on the front. Fits my medium-sized hands extremely well, just like the original P226 Legion.
3:34 The mag release sits out a little further with nice texturing — very easy to manipulate without breaking my grip.
3:49 The trigger is extremely nice. Flat face, adjustable, single-action-only. Very little take-up, light crisp break, short and tactile reset. This is above the already good original Legion trigger.
4:23 Trigger pull on this well-used range gun is coming in right around 2 lbs. Absolutely phenomenal.
4:39 You have a 1913 Picatinny rail up front for lights or lasers. Ambidextrous manual safety with serrations — very tactile and audible.
5:08 The slide lock is a little tucked in next to the safety, so it can be slightly harder to manipulate, but not bad.
5:36 There’s a thumb rest / gas pedal on the side with texturing. I can get a very positive grip with my thumb — I really like this feature.
5:56 The slide has aggressive front and rear serrations. The action is extremely smooth, like it’s on ball bearings.
6:17 Optics cut with a SIG optic mounted directly. It also comes with SIG X-Ray sights, which I’m a huge fan of.
6:42 The big difference is the ported slide up front. This made a noticeable difference — smoother shooting with less recoil.
7:07 Takedown is a little different. Push the gas pedal, push the pin down, lock the slide back, and rotate the lever.
7:47 Inside, even though this is a well-used range gun, the fit and finish still looks fantastic. Two-spring guide rod and a 4.5-inch carbon steel barrel.
8:42 Shooting impressions: I went through about 300 rounds. It’s an extremely great shooter with zero problems. The ports/comp really help keep it flat. The trigger is phenomenal.
9:10 Do I prefer this over the original P226 Legion SAO? Yes, I do. It’s incredibly accurate — one of the most accurate guns I’ve shot alongside the Shadow 2. I’m a massive fan.
9:33 Price at the time of posting is around $2,200. Are they worth it? From my shooting experience today — yes, I think they are.
9:56 That’s pretty much it for me, folks. If you have any questions or comments, please ask them below. Happy to help out wherever I can. Until next time, I’ll catch you later.
