Round Butt Slim

Round Butt 1911 grips, also called Fastback 1911 grips, are built to fit the rounded frame 1911s like those built by Kimber, Sig Sauer and Smith and Wesson. The grips feature a covered pin with a relief cut on the back of the grip for the domed head of the mainspring pin. These are slim grips that are built to a thickness of about 0.16" and require slim 1911 grip screws and bushings.
