After looking into several manufacturing methods, we decided to fully machine the hammers from solid, the method we use for our popular hard sear, long ball head disconnector, slide stops and thumb safeties.
The accuracy of the hammer is impressive. Using one hold to machine and ream the holes, mill the profile, cut reliefs and slice the hammer means that all these operations will be within .0005″ for a true and square hammer. Vacuum hardened American tool steel 51-53 Rc hardness to hold the geometry for the life of the hammer…but not so hard that it becomes brittle.
The tank treads for cocking serrations look Heavy Duty and are functional without adding stress risers.
