Glocks do very well underwater so far as rusting, etc., is concerned.
Obviously polymer parts are impervious, and most metal parts in Glocks
are tenifer-coated. Those that aren't are parkerized or hard-chromed.

Miami P.D. did their own salt water immersion tests during their evaluation
of the Glock pistol and the only problem was some salt and other residue
build-up internally. They locked back the slide, swished the pistol around
in a bucket of kerosine, loaded it and it fired flawlessly.

Model 18 Glocks are routinely cooled by unloading them, locking back the
slide, and holding them under (preferrably running) water. Remove water
from the bore and resume firing.

Glock makes underwater spring cups especially for underwater firing, but
they are available only to special military units, and even then a waiver
must be signed concerning their use.
