Sig Sauer’s remarkably ergonomic P227 is a .45ACP with a 10+1 capacity, but you would hardly know it from the thinness of the grip. It fits most holsters designed for P220R and P226R. This DA/SA pistol has an alloy frame with an integral accessory rail and has a black hard coat anodized finish. The stainless steel slide sports a black hard coat anodized finish and Siglite night sights. It has one-piece enhanced E2 grips.
