This set of 1911 grips are made in the USA by Altamont Grip Company. They are made from bonded ivory, a manmade material . The oak leaf pattern has a stipple-style background surrounded by an engraved edge border. The deep grooves give you a good grip, and are smooth – they will not ‘bite’. I guarantee the fit for most standard 1911 frames and they are backed up by Altamont’s lifetime guarantee.
