The Align Tactical(TM) OFFSET EXTENDED MAGAZINE RELEASE allows the operator to rest their distal middle finger flush across the lower half of where the Sig SauerA(R) P320 (M17/M18)A(R) factory magazine release's triangular bottom edge would be, eliminating side-finger chafing when choking up high on the pistol grip for increased recoil control. Ergonomically designed with an enhanced and extended engagement surface closer to the thumb, for minimizing/eliminating pistol shifting in-hand when reaching to eject magazines. Obtain the highest grip with an unobstructed undercut that allows natural finger placement, thereby reducing muzzle flip to return the sights back to target Mfg: Align Tactical
