My gun is custom modified for high grasp double action shooting. That is why it has the full trigger and action job consisting of the Apex Evolution IV parts kit and a level IV ICORE action work. If the hammer had not been changed out for a hammer-less model you cannot use the high grasp to control the revolver better in rapid fire as the back of a normal hammer will hit your hand. It is all in what you plan to use the revolver for.

Originally designed as a semi-drop in replacement for Performance Center revolvers, the Apex Evolution IV N-Frame Hammer is redesigned using the same pinned sear and stirrup found on the Performance Center hammer. Additionally, the Apex Evolution IV Hammer replaces MIM components found in Smith & Wesson non-Performance Center revolvers and Performance Center revolvers made after January 2012. Manufactured from heat treated 17-4 Ph stainless steel, the hammer is wire EDM and CNC machined then surface ground to ensure consistent performance.
