Re-designed and flawlessly CNC machined from hardened, billet tool steel, the button of the Wilson Combat Bullet Proof Tactical Magazine Release is slightly extended 1/16" over a stock part for fast, smooth operation and is equally suited for competition or carry. Perfectly checkered at 30 LPI for non-slip activation and engineered to maximum drop-in tolerances, this easy upgrade will improve the feel and performance of any 1911 pattern pistol. Minor fitting may be required. Magazine catch lock and spring not included. It is crafted from stainless steel.
