Wilson Combat hammers are manufactured from the best quality steel to keep that clean crisp trigger pull shot after shot. Considerable attention has been paid to the geometry of their hammers, particularly to the location of the strut pin hole which has been re-located to aid in obtaining a light trigger pull. Experience has shown that their advanced hammer design enhances reliability and the ability to consistently produce a crisp, yet safe trigger pull. All Wilson hammers have been narrowed to provide adequate slide/hammer clearance and some are skeletonized to improve lock time. It is worth noting that skeletonizing a hammer improves the speed that it travels, which in turn reduces lock time. It does not effect the trigger pull. The Skeletonized Ultralight Hammer is fully CNC machined from solid S-7 tool steel bar stock and heat treated to R/C 48-52 to produce the finest 1911 hammer on the market. This hammer features a skeletonized spur for minimum weight and fastest possible lock time, hammer hooks cut to .020" with 8 RMS ground finish and narrow half-cock notch to prevent sear nose damage.
