    haha. I guess that did sound like something that Johnny Knoxville and Stevo would have dreamed up.

    The sound would be nowhere near as loud as a powerhead, which is a little startling, but not painful.

    Get concerned about the pellet going anywhere. In water, the length to cross section ratio becomes a big deal.

    The punch from that pellet comes from it moving at a few hundred feet per second. That is not going to happen underwater. The mass and shape of the projectile are all wrong for delivering energy in water.

    So it makes sound. So what?

    Bullets shot from rifles into the water from above only have limited penetration abilities. The water absorbs the energy quickly. A .223 or 30-06 cartridge shot from a powerhead underwater only goes a few feet after going through even a small fish or if pre-ignition happens. Any of these projectile will weigh up to 50 times more than a pellet so I would think that the pellet would fall off in a hurry. I've heard many times that Glock pistols will work underwater. There's a story about Cali. abalone dovers carrying them for shark protection.

    You biggest concern is sound? Is there something you are not telling your buddy? LOL

    any pistol will fire underwater provided you use ball ammo - hollow points will destroy the barrel as they begin to expand before exiting the barrel due to the resistance of the water.

    My pellet gun has a muzzle velocity of 950/sec. I guess this is the speed of the pellet as it leaves the gun barrel. But, if it's fired under water, and the barrel is full of water to begin with, it will never attain that velocity. I may not even make it out of the barrel.
