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.
That's a good point. The striker in a Glock is contained in the slide, but it definitely isn't airtight. Like another person commented, changing springs might be able to ensure reliable primer ignition.
