The Sig Sauer P220 Legion 10mm is a purpose-built full-size pistol for serious shooters who demand both power and precision. Built on the proven P220 platform and finished in Sig's proprietary Legion gray coating, this 5-inch barreled 10mm combines classic single-action/double-action ergonomics with modern tactical refinements. It's equally at home on the range, in competition, or in the field—a no-compromise platform for hunters and defensive shooters who value the stopping power of 10mm Auto.
Every detail of the Legion points to purposeful engineering. The stainless steel slide wears SIG SAUER X-RAY3 high-visibility day/night sights and front cocking serrations for reliable function and fast sight control. The frame is stainless steel with Legion gray finish, and the grip is black G-10—textured, durable, and designed for all-weather use. Up front, aggressive checkering on the trigger guard and forward strap, combined with an X-Five undercut, locks your hand in place under recoil. The reduced, contoured Elite beavertail rides high and keeps a low profile, critical for comfortable carry and solid control without printing.
The trigger system is where the Legion truly shines. Sig paired their enhanced Short-Reset Trigger (SRT) with a P-SAIT trigger design by Grayguns Inc., resulting in crisp, predictable break and immediate reset. Low-profile decocking and slide-catch levers minimize snagging risk. A solid steel guide rod adds mass in the right place, smoothing the firing cycle and improving shot-to-shot performance. Three 8-round magazines ship with the gun, giving you plenty of capacity out of the box. The SIG Rail under the trigger guard accepts standard accessories, and the pistol is optic-ready for those who want to mount a red dot.
At 44 ounces and 8.8 inches overall, the P220 Legion balances heft and shootability—heavy enough to manage 10mm recoil, compact enough for serious carry and field work. The 7-inch sight radius aids precision at distance. This is a pistol built for shooters, not committees.
