Wilson Combat 337B Ultralight Skeleton Hammer

Wilson Combat 337B Ultralight Skeleton Hammer

Wilson Combat has engineered this skeletonized hammer to deliver the performance that serious 1911 shooters demand. Every aspect of its design reflects decades of refinement in 1911 mechanics.

Superior Materials and Construction

The 337B is fully CNC machined from solid S-7 tool steel bar stock and heat treated to R/C 48-52 hardness. This process produces a hammer of exceptional durability and reliability that will function flawlessly through thousands of rounds.

Performance Features

Skeletonized Design: The reduced mass of the skeletonized spur decreases lock time—the interval between trigger press and firing pin impact. Faster lock time means more consistent shot placement, particularly important in precision shooting and competition.

Precision Geometry: Wilson Combat has relocated the strut pin hole to optimize trigger pull characteristics. The hammer hooks are cut to .020" with an 8 RMS ground finish, ensuring a clean, crisp break without creep.

Safety and Reliability: The narrow half-cock notch prevents sear nose damage during handling. The narrowed hammer body provides adequate clearance with the slide while maintaining the structural integrity necessary for safe, reliable operation.

The Bottom Line

This is a hammer built for shooters who understand that small improvements in mechanics compound into measurable performance gains. Whether you're building a custom 1911 or upgrading an existing firearm, the Wilson Combat 337B delivers the quality and precision that defines the brand.
