Action rifles such as the AR15 or AK-47 are ideal defensive tools. They are the easiest to shoot, have twice the capacity of a typical pistol, low recoil, and compact in size.

This is because they shoot very light bullets moving at very high velocities. Therefore, contact with any medium will cause them to tumble and rapidly lose energy unlike pistol bullets and buckshot pellets (which retain their energy and can penetrate several layers of wood and sheet rock).
