This single-piece grip slides on revolver frames from the bottom, requiring no modification to the firearm. A patented steel "stirrup" device clips over the existing stock pin or bottom strap of the frame. The stirrup is the key component in the system that adapts the grip to the gun handle. Monogrip allows a high handhold on the backstrap which lowers the bore line, reducing muzzle rise in recoil and aiding rapid-fire recovery time, especially when using a two-hand hold. Palm swells are ambidextrous, allowing equal comfort and control for either right- or left- handed shooters.
