SIG Sauer
P220 platform chambered in 10mm with Legion trigger work and X-RAY3 sights
0-10 Scale Across 8 Axes
SIG Sauer applied the Legion treatment to the P220 in 10mm, producing the finest DA/SA 10mm pistol available. The P220 platform has decades of proven service in .45 ACP with the same operating pressure class, so the transition to 10mm is mechanically straightforward. Legion upgrades include a reduced and polished DA trigger (10 lbs), crisp SA pull (4.4 lbs), X-RAY3 day/night sights, G10 grips, and an accessory rail.
The DA/SA action offers a meaningful safety advantage for field carry: the long, heavy double-action first pull provides a deliberate firing sequence without requiring manual safety manipulation. For backcountry carry, where a pistol may be holstered for hours before sudden deployment, the DA first pull provides confidence against negligent discharge while the short SA follow-up pulls deliver the accuracy needed for a fast second shot.
The P220 Legion 10mm is a single-stack 8+1 design, carrying the same capacity limitation as the 1911 options. At $1,449, it commands the highest price in this guide. The value proposition is the trigger: SIG Legion DA/SA work produces the smoothest, most consistent double-to-single transition on the market, and the X-RAY3 sights are among the best factory night sights available on any pistol.
