Id go the water resue route. Theres got to be one in that county somewhere.Might cost youa "donation" to the Fire or Rescue team but $100 spent to get your gun back is worth it. Or if you want to rambo it, wear some clothes and carry a change of clothes. (youll be warmer in a full set of wet clothes until you can change than you will be in a bathing suit) Find it again with the magnet and jump in. If you change into dry clothes ASAP you'll be fine.
