I bought a colt BP revolver at the gun show a couple weeks ago. It's brand new in the box and still has the old grease on it. I was taking it apart and realized that my wedge won't go all the way thru the base pin. I have a small hard plastic hammer so I drove the wedge all the way in as it should be. This locked up my cylinder though. Now when I remove the cylinder, it goes in the base pin fine and thru the barrel slot fine. Anyone have some suggestions what the problem might be? Am I going to have to file it down inside. I can see the wedge trying to go in crooked after I insert it but no way of making it go straight in. Thanks for any help!
