The Cammer Hammer is a replacement hammer for M1911-style pistols that is CNC-machined from 17-4 stainless steel bar stock. The hammer face exhibits a custom contour that the company claims reduces felt recoil and the force required to rack the slide. The unit is heat-treated for additional durability. Price: $98.
