In reference to your section on shooting a Glock underwater I would like to add a few important facts. Where did everybody get the idea that firing a gun underwater will damage your ears or organs? Firing a pistol underwater will not damage your ears or organs. I've shot 1911s years ago underwater, fully submerged. We used to kill sharks (before it was un-PC) with a device called a "bang stick", a 44 mag barrel on the end of a 6 foot long solid aluminum shaft with a sleeve to accept the barrel and a solid firing pin on one end and surgical tubing on the other end used to propel the barrel into the shark. The barrel was held in the sleeve with an "O" ring but the barrel would fly out of the sleeve when it went off (this was real neat because the case would usually fall also, making reloading easier) but was held captive to the sleeve with a steel cable. The bang stick even had a safety pin through the sleeve to prevent accidential discharge. We used nail polish to seal the primer and bullet. I once used the bang stick to blow the trunk lock off a car I found in a quarry at 60 feet deep while searching with the local PD to find a gun used in a murder. I have used bang sticks over 100 feet deep. The sound when firing a 44 mag underwater is just a dull whump, so anything fired out of a Glock would be insignificant. Believe me you have a lot better chance with a bangstick than 10 Glocks against a shark unless you want to hold the Glock barrels against the shark, no easy feat, I would rather keep the distance provided by the bangstick between me and the shark. As the NAUI instructor said the most important element was the gasses, there was also a device made by a company called Farallon that used a CO2 cartridge with a long hollow needle screwed on the CO2 cartridge, this was mounted in a sleeve on a rod similar to the bangstick, almost any solid body hit would blow the insides of the shark out of his mouth and float it up to the surface out of your way.
