SIG Sauer's P227 SAS Gen 2 provides more power per square inch than any other pistol on the market. The remarkably ergonomic P227 is a .45 ACP that holds 10+1 rounds, but you'd hardly know it from the thinness of the grip. Every P227 has a double-action/single-action design and fits holsters designed for P220R and P226R. This version has a shorter 3.9" barrel to make holstering easier. Take hold of this high-power, high-capacity pistol and you'll see first-hand how SIG's stacked the odds in your favor.
