The 1911 Government model auto is about as rugged as a mountain mule, but when you take the grips off to polish and reblue the critter or put on another set of grips, chances are that the stock frame bushing will be stripped. And, when you remove the frame bushings to get the best polishing job on the frame, you’ll find yourself looking for new bushings. Standard Stock Bushing - Nicely made and finished, these special-sized, bushings are packed in sets of 4 Bushings. Stainless Steel (S/S) Stock Bushing - Look “right” on stainless steel and nickel-plated guns.
