It's a 12 gauge pump. Older model - "Ranger". There's a round in the chamber. Doesn't appear to have a safety. There's a small sliding type button behind the trigger guard that doesn't slide. The gun has not been cared for. I need to get it unloaded for transport. Can't leave it in it's present location, loaded or not. Anyone know how to safely get the round out of the chamber without firing it?
