Barrel. Yesterday I got a deal on an octagonal but unused barrel for a Contender. I put it on a newer (but still old) frame and it is locked up so cannot be reopened. Can anyone walk me through the steps to get it off. I have already removed the grip and the hinge pin but have not tried "brute force" yet? I assume I will have to do some limited disassembly, of course. Luckily I have other frames that I know that barrel will fit on.
