This product was developed after understanding that grip is one of the most important things in regards to shooting a pistol faster with more control. I tried using standard grip trainers off Amazon, 50, 100lb, etc, and those were great at strengthening your grip, but I found myself wanting to combine the grip of a pistol and the grip strengthener together. You will be able to strengthen your grip on your pistols exact grip. A grip strengthener that matches your pistol will lead to improved recoil control, and stronger fundamentals since you will be able to train with it anywhere you wish. The Grip Keeper is a diverse tool any gun lover can use. Competition shooters can use this for warming up your grip before a stage. Police officers can use it in their cars while waiting for a call. The general user can use it to strengthen their grip for the pistol incase a defensive situation arises. Get a Grip Keeper that matches your pistol and feel more confident with your every day gun.
