Having spent some time fishing the cottonmouth filled waters of Alabama and Louisiana, I have witnessed the need for these 4.10 / 45 life savers. The cottonmouth is notorious for wanting to climb in your boat. Not because he is out to get you, rather he wants to have a rest while swimming and your boat looks just like every other floating piece of driftwood. Word of warning.... Do NOT let one in your boat.... the snake slayer will do the job but my preference tends to lie with the Taurus "Judge" and only because it chambers both the 45 and the 4.10 in a 5 round revolver setting. So in theory, 2 is good.... 5 is better...
