Pachmayr's Compac Grips are made from a specially formulated black rubber compound and are designed to maintain concealability. Although compact in design, Compac Grips still give a shooter total control; Compac Grips provide a secure, non-slip finish. That's why they are the plainclothes officer's preferred way to a more positive grip without compromising concealability. Product Specs: Fits Smith & Wesson "J" Frame Round butt grip
