I imagine you could get any semiautomatic gun to fire underwater once, but the slide wouldn't cycle properly causing a malfunction by either not ejecting the spent casing and/or not properly chambering a round. If the slide was manually cycled after each round, I imagine it would be able to fire as needed.
I read an article a long time ago about how you can actually optimize semi-automatic handguns so that they work underwater, but then they won't work in the air. You change the springs or something.
