The M45A1 CQBP is manufactured from forged stainless steel. The receiver, slide, slide stop and barrel go through a forging process to make the steel stronger and tougher as well as to hold tolerances more closely. The finish spec called for a dull, non-reflective surface, so it wears a desert tan Cerakote finish. The barrel is match grade. It wears a UID (unique identification) label on the receiver, which is a 2D Matrix symbol that contains data and can be read by a reader camera, similar to a barcode. Other features include a dual recoil spring assembly so recoil feels softer, an integral Picatinny rail so the gun can incorporate a tactical light, an upswept grip safety and an ambidextrous manual safety, a long solid trigger, a flat mainspring housing (like the original M1911), texture G10 grips, and Novak 3-dot, Trijicon night sights. The M45A1 is fed from seven-round Wilson Combat magazines.
