Colt Lightweight Commander Series 70 9mm – 4.25" Alloy-Frame 1911, 1972 Production
This 1972 Colt Lightweight Commander is a first-generation Series 70 9mm 1911 built on Colt’s alloy “Coltalloy” frame. Weighing about 27 oz and retaining the crisp pre-Series 80 trigger, it offers the classic Commander profile with reduced weight and an early factory 9mm chambering that remains scarce and collectible.

The Lightweight Commander pairs a forged steel slide with a matte black aluminum alloy frame, shaving significant weight compared to a full-size Government Model while retaining the familiar 4.25-inch barrel. The polished blue slide carries vertical rear serrations and fixed GI-style sights that are low profile yet easy to track.
Chambered in 9mm Luger, this Commander was among Colt’s earliest factory 9mm 1911s. The CLW serial prefix confirms its 1972 production and alloy frame, adding collector appeal for those seeking pre-Series 80 construction without a firing-pin safety.
A ring hammer, short aluminum trigger, and original Series 70 internals deliver the light, consistent single-action break enthusiasts value. Standard 1911 controls—grip safety, manual thumb safety, and half-cock notch—provide familiar, trusted operation.
The replacement smooth walnut grips with inset Colt medallions offer a clean, classic look while the alloy frame keeps overall weight manageable for carry or range sessions.
