What gun would you bring along in your kayak for problems or just if you see a nice juicy squirrel?

I pack a Henry 22 survival rifle, it fits into the butt stock and its supposed to float but I've decided not to take that chance, I'll upload some pics of it soon. If a problem comes along (snake of course) or if I see a juicy squirrel while parked camping for the night, yeah sometimes hotdogs and brats are just not enough. Its light and made to take the tough weather, the barrel is plastic coated and the reciever is made of rust proof alloy. This is for rain by the way, not swimming under water and coming up and destroying something like on tv! I've found it to be accurate and very dependable. More later.
