Wilson Combat's re-designed and flawlessly CNC machined from hardened, billet tool steel, the button of our 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. Note- Magazine catch lock and spring not included.
