Description
The Mac 1911 Bobcut is a precision-machined slide assembly designed for 1911 platform builders. Manufactured by Mac’s Armory from 4140 steel, it features a distinctive bobbed rear profile for a streamlined, carry-ready silhouette. The slide comes with a durable black nitride finish and is fully compatible with standard 1911 Government model frames and components, offering a direct upgrade path.
Key Features
- Bobbed rear slide profile reduces snag points and overall length
- CNC-machined from solid 4140 steel billet for strength and precision
- Black nitride finish provides superior corrosion resistance and a low-glide surface
- Pre-cut for standard 1911 dovetail sights and series 70/80 firing system parts
- Designed for drop-in compatibility with most Government model 1911 frames

The 1911 Bobcut’s design centers on the bobbed rear contour, which removes material behind the ejection port. This reduces mass for potentially smoother cycling and creates a shorter overall slide length, a functional advantage for concealed carry. The 4140 steel construction, hardened via nitriding, ensures long-term durability under the high-pressure stresses of .45 ACP or 9mm chamberings, maintaining critical tolerances for reliable operation.
