Key Features
- Optics-Ready Slide: Cut for the SIG Romeo2 footprint, so you can mount a red dot without sending the slide to a machine shop. Why it matters: You get faster target acquisition and a lower bore axis without losing your irons.
- XRAY3 Day/Night Sights: Tritium inserts with a bright front ring. Why it matters: You see your sights in any light—dawn, dusk, low-light indoor ranges—without batteries.
- Reduced Elite Beavertail & X-Five Undercut: Lowers the bore axis and lets you choke up high on the grip. Why it matters: More control equals less muzzle flip and faster splits on .45 ACP.
- G10 Legion Grips with Medallion: Aggressive texture that locks your hand in place, wet or dry. Why it matters: No slipping during recoil, and the medallion tells everyone you’re running a Legion.
- Three Eight-Round Magazines: Comes with three flush-fit mags from the factory. Why it matters: You get more range time and less reloading right out of the box.
Who It’s For
This pistol is for the shooter who wants a .45 ACP that’s ready for duty, competition, or home defense without needing aftermarket work. It’s for the guy who appreciates a tuned trigger, a beavertail that actually works, and a finish that holds up. If you carry a .45 for work or run one in USPSA Single Stack, this Legion is a no-compromise option.
Pros & Cons
- Pro: Factory optics cut means you save $100+ on milling. Pro: The Legion trigger has a clean 4.5 lb break with short reset. Con: The proprietary Legion Gray finish is durable but can show holster wear over time—it’s not Cerakote. Pro: The X-Five undercut is comfortable even for shooters with larger hands.

The Zev OZ9 and Geissele Duty are excellent 9mm striker guns, but the P220 Legion is the only one that brings a .45 ACP caliber, a DA/SA trigger with decocker, and a factory Legion tune. If you want a .45 with a proven track record and factory upgrades, this is your pick.
FAQ
Is the SIG P220 Legion optics-ready right out of the box?
Yes. The slide is cut for the SIG Romeo2 footprint. You can mount a Romeo2 directly without any adapter plates or milling. If you prefer a different red dot, you may need a plate from SIG or a third-party shop.
Does the P220 Legion come with night sights?
Yes. It ships with XRAY3 day/night sights. The front has a tritium vial with a bright green ring, and the rear has two tritium dots. They are steel and drift-adjustable.
How many magazines are included?
Three eight-round magazines are included. They are flush-fit and use the same P220 8-round mags you can find anywhere.
Is the Legion Gray finish durable?
It’s a proprietary SIG coating that resists corrosion and wear better than standard nitron. That said, it can show holster wear on the slide corners over time. It’s not indestructible, but it holds up well for a carry gun.
What is the trigger pull weight on the P220 Legion?
The double-action pull is about 10 lb, and the single-action pull is a clean 4.5 lb. The reset is short and tactile, typical of the Legion trigger job.
