A friend of mine is an avid bass fisherman. He primarily fishes the swamps which are loaded with snakes, to include water moccasins. His primary deterrent is a 642 loaded with CCI snake shot. He had a local gunsmith mill a pined hole in the backstrap for a lanyard attached to his belt. That way he cannot lose the gun. The moccasins are known to drop into boats as they cruise by from overhead tree branches. The snake shot is very effective. I have a 642 that is carried as my summer/hot weather front pocket gun. Love that little wheel gun.
