The GI Frag grip panels are inspired from the Mk. II Pineapple grenade, used in WWII. The Frag pattern provides superior grip while avoiding overly aggressive checkering which can cause pain after extended shooting. Keep your pistol where it needs to be without sacrificing comfort. Machined from billet aluminum and hard anodized. Will fit government and commander size 1911's. Available in flat bottom for standard magwells, flat bottom for the Tech-Well magwell system, or standard government bevel. All grips are cut for ambidextrous safety.
