Cool Fire Trainer Kit 

Dry fire allows you to focus on the process of breaking the shot not the actuall shot score. This way you can improve many aspects which are hard to see when you train live fire. But there is serious limitation with semi-auto firearms because for each dry shot the trigger needs to be reset manualy. It makes dry fire useless for more complicated drills. Now Cool Fire solution will not only reset your trigger after each shot but also simulate recoil of the gun. Now think about the drills you could make in your home . . .
