The instructors for Magpul's training division wanted a 1911 grip with advanced features, improved control characteristics, and Magpul value. These grips were designed with their input and testing. Constructed of carbon-reinforced polymer, the grips have a unique diamond-shaped cross section to prevent twisting in the hand, an aggressive magazine release cut-out, aggressive texture for positive control, and are compatible with ambidextrous safeties. The grips are designed to fit full size framed 1911s with standard grip screw bushings. Made in U.S.A.
