Be careful with that here in NJ as our firearms laws are very strict. Being from out of state, I'd hate to see you get jammed up. Tournaments usually forbid their use, as well as harpoons and guns, so it is a good idea for your shark crew to get used to keeping sharks without such methods, so when possible prize money is on the line, you are just doing what you are used to doing, not something new. Get a tail rope on (attached to a cleat) and your good to go.
