Overview

The springfield 1911-a1 mil-spec 45acp stainless steel is built on a forged stainless steel frame and slide, heat-treated to military specification.

Every component, from the Parkerized internal parts to the matte stainless finish, is engineered to mirror the 1911A1 pattern used by U.S. forces. This pistol is not a custom or competition variant; it is a strict mil-spec reproduction designed for service life and field reliability.
