That's a big gun!

I agree it probably a beretta M92.

The cavitation in the Gelatin was amazing.

I'm afraid I can't accept the stuff about air rushing back into the barrell causing recoil. a) I'm not sure there will be such a hard vacuum left in the barrell and b) the area of the bolt face is so small that the 15 psi of pressure at max won't do much.

That said your explanation makes sense of the muzzle brake/compensator. If you can give me a link to another explanation...please.

I must admit though being English I don't get to see guns that often so I'm working just from physics.
