Besides controlling muzzle jump of firearms, therefore improving speed and accuracy, Smart Lock Technology's Recoil Control Thumb Rest can also prevent slide cuts to the web of the shooting hand, and improve high thumb hold and indexing of the firearm. With an ambidextrous design, and when shooting with weak hand only, it can reduces the muzzle jump by almost 70 percent. It installs over the existing trigger housing pin location and no modification is required. The Recoil Control Thumb Rest is available for Glock, Springfield XD and Walther/S'W P99.
