The Right-Sized Stone For Semi-Auto Pistol & Revolver Work
This is one stone you really need to have in your tool box. We had it specially made for one function, then, as we used it, we found that it works great for many others. Precision-cast, ceramic stone is an exact fit for smoothing the inside surface between the frame tangs on a 1911 Auto. A smooth surface gives improved hammer function and a lighter trigger pull. Also fits the hammer slots on all Ruger "P" Series Pistols, all Ruger Revolvers plus all S&W K, L, & N frame revolvers. We didn't plan on such a versatile stone, but we're delighted it turned out that way.
