The Colt M1911 is a single-action, semi-automatic pistol that uses .45 caliber projectiles. This high-caliber weapon is powerful, considering its light weight. It is the only semi-automatic pistol the player can use in Mirror's Edge. Miller holsters a pair of these powerful pistols. His sidearms are either nickel plated or stainless steel.
This weapon appears for the first time (excluding training) wielded by the "Blues" when you drop from the vents in the first level. There is also one on the table in Ropeburn's office. The in-game version holds 9 rounds at a full magazine. Conserve your ammunition, take aim and cover, and shoot with care. It isn't a strong weapon, but it would take down even the toughest PK officer with several bullets.
