What would happen if you shot a Glock 9mm underwater?
Twang N Bang is ready to try out shooting a Glock pistol underwater.
Witness what happens when a Glock 9mm pistol shoots underwater.
Bang N Twang is tackling a question many have asked. Can a pistol fire underwater and how powerful would it really be? We are about to find out.
Armed with a Glock 17, he changes out one sub assembly, the spring cup. He inserts a maritime spring cup that is meant to allow better functioning of a Glock underwater. He finds that shooting underwater is indeed a reality. It is also very rough on the shooter with heavier recoil and underwater concussion. That just might rattle you a bit. Ballistic gelatin blocks do indeed get nailed underwater but at lower bullet velocities due to water density.
