SIG Sauer's P227 provides more power per square-inch than any other pistol on the market. The remarkably ergonomic P227 is a .45 ACP that holds up to 14 rounds, but you'd hardly know it from the thinness of the grip. Every P227 has a double-action/single-action design and an integral accessory rail and fits holsters designed for P220R and P226R. The Tactical Operations model features SIG's Short Reset Trigger, custom G10 grip plates with a mag well, a TruGlo tritium fiber-optic front sight, and front cocking serrations. Four 14-round extended magazines are included.
