With the HK P11, you should be able to carry a few of the loaded barrel units. Kind of like the old black powder guns where some gunmen would carry several loaded cylinders (of course back then those things had a tendancy act like grenades at inconvient times...)

note: I'm talking in the SR world when I reference the P11...I think it would be a bit of a hassel for some pirate/runner to send his or her piece back to HK, Germany after every 5 clicks.

Wouldn't a sound gun be a decent idea for underwater? Heck, if the submarines are apparently killing whales, then shouldn't we be able to get people?

Though, that would be a pretty small target market for a company "Er, we spent thousand on R&D to make sound guns ... who buys them? Er, underwater security guards"

Well, you could adapt some sort of (largely superscience I'm afraid) saser into Shadowrun. SR has some pretty remarkable fantasy weapons physics so I don't see why it wouldn't work. You could use a laser but those will realistically attenuate VERY quickly in the water, even everyone's favorite "blue-green" versions.

Rather then underwater guns (which if you look are really just glorified spearguns) you could try small minitorpedoes. You're probably not going to get very good performance until you get to 60mm+ but they can at least theoretically be guided and carry a explosive punch.

Supercavitating weapons do not exist in Shadowrun at last check, so that rules out the best opportunity for underwater/air-water boundary projectile weapons.

I hate to be a walking advertisement, but I do suggest checking out Transhuman Space: Under Pressure for advanced underwater equipment, rules, and general technology.
