Well the reason I am asking is I got a new gun case for this gun for Xmas, but it doesnt fit with the supplied lock on it because the gun is broke open. I've never actually tried to fire the gun by pulling the hammer half way back, I just assumed that that was the logic behind the type of lock that the gun comes with. I have children, and take precautions (don't keep the ammo in the same place, keep the guns out of their reach for the most part, etc.), but I'd like as much security as I can get. I dont use this gun for personal or home defense, so I am not all that concerned with having it readily available. If it gets down to pulling the slug gun out, I am in trouble! Or someone else is.....
