The Apex Tactical Evolution IV Hammer Kit is designed for Smith & Wesson K-Frame and L-Frame revolvers and converts them to double action only. It utilizes the same pinned sear and stirrup as the performance center hammers and replaces the weak MIM components with fully machined 17-4 stainless steel components. The hammer is EDM cut, CNC machined, and then surface ground to ensure consistent performance. Some fitting may be required.
