This video shows you what I've done to improve the gun handling by molding the grip to increase the frictional surface. The more surface that has a good solid contact with the palms of your hands will result in better ability to absorb recoil. I also talk about how you can rack your slide and recover your grip faster !
To customize your grip you'll need:
A set of aluminum grip panels
Molding Putty
Grip Tape (Skateboard Tape / Skid Tape)
