Gill Arm Lock TM is an innovative new device that reduces muzzle rise and felt recoil of pistols. When cartridge is fired from pistol, forward end of the pistol rises upward because barrel axis lies above the arm. When Gill Arm Lock TM is installed on the pistol, aft upper arc lies above the forearms of the shooter and restrict muzzle rise of the pistol. Sorbothane® pad absorbs shock energy hence increase accuracy and shooter is able to engage to the target more efficiently for subsequent round.
