Wilson Combat 337S Ultralight Skeletonized 1911 Hammer

The Foundation of a Superior Trigger

A quality hammer is the cornerstone of any fine trigger job. Wilson Combat's 337S Ultralight Skeletonized Hammer represents the pinnacle of 1911 hammer design, engineered to deliver the crisp, reliable trigger pull that serious shooters demand.

Superior Materials and Construction

This hammer is fully CNC machined from solid S-7 tool steel bar stock and heat treated to Rockwell hardness 48-52. This process produces a hammer of exceptional durability and consistency—the kind of precision engineering that separates quality components from the rest.

Optimized Design Features

Wilson Combat has paid considerable attention to hammer geometry, particularly the relocation of the strut pin hole to aid in achieving a light trigger pull. Key design elements include:

• Skeletonized spur for minimum weight and fastest possible lock time
• Hammer hooks cut to .020" with 8 RMS ground finish for reliability
• Narrow half-cock notch to prevent sear nose damage
• Narrowed profile to provide adequate slide/hammer clearance

Performance Benefits

Skeletonizing the hammer improves the speed at which it travels, which in turn reduces lock time—the interval between trigger press and firing pin strike. This translates to faster, more responsive shooting. The advanced geometry enhances both reliability and your ability to consistently produce a safe, crisp trigger pull.

When you build as many custom pistols as Wilson Combat does, you learn the true value of a quality hammer. This is a component you can count on.
