I got my 1980 Heritage Walker in today, and looks like it's never been fired or turned. I wanted to take a look inside the barrel, but I can't get it apart. I have a 1860 Colt Army, and I assume it's basically the same (tap wedge out, and pull so the 2 little pins come out in the bottom front of the frame).
Not sure if the 27 years of laying in a case has anything to do with it.
Any ideas?
