I haven't done this. But I was curious, what do you do after you drop your firearm in water? Maybe it was a lake, a pool, whatever. What should one do?
Since I know what you shoot, pull the trigger:
YouTube - Glock 19 underwater
just kidding, you need some mods to do this reliably.
I blow the duck call until they fly by once, say about a dozen F-Bombs as I freezzzze my arm off looking for it and then hope they swing around for a second look at the dekes!!!!!
