Sig Sauer 1911X .45 ACP 5" Semi Auto Pistol

The Sig Sauer 1911X is a full-size, single-action semi-automatic pistol chambered in .45 ACP, built around the traditional 1911 operating system and modernized with SIG Sauer features. Its 5-inch barrel and full-size frame suit defensive, sporting, and recreational shooting, while the 8-round detachable magazine keeps the classic single-stack profile.

The slide is cut for a compatible reflex sight, so you can run iron sights or add an optic as your setup changes. Night sights come standard, and the stainless steel frame wears a Cerakote finish in a two-tone black configuration.
