As I understand, to get the Glock to fire underwater you normally need to install marine (or maritime) spring cups. They are super cheap but allow it to cycle normally. I'm sure the ammo has to be somewhat specialized so as not to adversely affect the environment but otherwise the Glock excels here because it is so customziable.
