Having a firm grip on your semi-automatic handgun is key for several reasons, the most important of which is to avoid what's commonly called "limp wristing" the gun. When a shooter has a weak or loose grip on the gun, it usually results in the firearm not cycling properly, causing the gun to jam. A firm grip will also help you on assignments, where you need to fire from a marine platform. Read "Perfecting Your Handgun Grip" for more. Photos courtesy of Michael Rayburn.
