Chaz: Depends on the gun. Generally speaking if a cigarette paper can't be withdrawn when the action is closed it considered to be "on-face". If it's a Purdey or a Parker or any high grade gun you probably wouldn't want to donate it to CB. I doesn't cost a bunch to have a good gunsmith put a double back "on face"
What kind of gun are you talking about.
