If you got a bang-stick - I'd just use it. End result for the shark is the same with either that or a pistol. Bang-stick much more effective with no risk of ricochet. IF it is really illegal to dispatch a shark - that you intend to KEEP - with a bang-stick, well then that is a law that was written by some douche-bag politician that probably doesn't know his a$$ from a hole-in-the-ground in the first place.
