can a regular 9mm pistol fire underwater ?

Most normally guns will fire underwater due to the chemistry in the gunpowder. There is enough oxygen in it that will let it fire just not as strong as when its in air. If you stick your finger in the barrel of a gun underwater your just gonna get your figure shot off.I've never heard of any one putting condoms on pistols.Mostly its rifles.They dont use them to fire guns underwater its actually to keep stuff from getting down the barrel.

Mythbusters did it, a 9mm will fire, but it will not reload correctly. Do not fire a shotgun under water, it will blow up in your face.
