Awesome. I saw this the other day, and along with the revolver and the explanation of the particular kind of vortices (toroidal) the muzzle blast produces, I am 99.99% sure the gun in question is a P95DC.

The frames from 3:00-3:15 are fascinating because you can *see* the polymer frame flex as it absorbs recoil energy from the slide. You understand in an instant why the polymer guns (when properly designed) have a reputation for their calibers as being "softer shooting" - the gripframe flex/whip is completely clear: the gun is absorbing some of the recoil energy through the flex of the frame, it's like a spring. You can also see by comparison with the revolver how much more efficient a locked-breech semiautomatic design is at getting the expanding gases down the barrel instead of out the sides of the gun. It's very, very clear.
The gun survives the completely submerged test and lives to fire again!
