Wilson Combat 337S Ultralight Skeleton Hammer - 1911 Style, Stainless Steel

The Wilson Combat 337S Ultralight Skeleton Hammer is a stainless steel 1911-style hammer designed for shooters building or tuning custom pistols who want measurable improvements in lock time and slide clearance. Unlike generic OEM hammers, Wilson Combat's skeletonized design removes material strategically to reduce overall weight and accelerate hammer travel—which translates to faster lock time between trigger break and firing pin strike. If you're assembling a precision 1911 or refining an existing build, this hammer is engineered to support the clean, consistent trigger pulls that separate a well-tuned pistol from a stock one.

Wilson Combat paid particular attention to hammer geometry during development, including the location of the strut pin hole, to facilitate lighter trigger pull tuning without sacrificing reliability. The hammer has been narrowed to ensure proper slide-to-hammer clearance, a detail often overlooked in budget parts but critical for smooth, trouble-free function. Stainless steel construction resists corrosion and handles repeated dry fire and live shooting without degradation—important when you're investing time and precision into a custom build.

This is the kind of component that matters when you're chasing trigger quality. Wilson Combat manufactures thousands of custom pistols annually, and that production experience shows in their attention to geometry and material. A skeletonized hammer won't change your trigger pull weight, but paired with proper sear work and a quality mainspring, it will help you achieve the fast, reliable ignition that serious 1911 shooters demand.

Frequently Asked Questions

Will this hammer work with my 1911 pistol?

The Wilson Combat 337S is designed for 1911-style pistols. Verify your specific 1911 variant's hammer compatibility before purchasing, as some models may have unique requirements.

Does a skeletonized hammer reduce trigger pull weight?

No. The skeletonized design improves lock time by reducing hammer mass and travel speed, but it does not directly affect trigger pull weight. Lighter trigger pulls require proper sear work and a quality mainspring in addition to a quality hammer.

What's the advantage of skeletonizing over a solid hammer?

Skeletonizing removes weight from the hammer, which increases travel speed and reduces lock time—the interval between trigger break and firing pin strike. This can improve ignition reliability and felt performance in a finely tuned 1911.

Is this hammer suitable for a custom build?

Yes. This hammer is engineered for custom 1911 builds and trigger jobs where precision and reliability matter. Wilson Combat manufactures custom pistols extensively, and their hammers reflect that expertise.
