I have a recently acquired Ruger Blackhawk (pre-warning label) in .357, and when I went out to test fire it, I had issues with the base pin walking out with every shot. After three shots, the pin moved enough to lock up the action until I would slide it back into place. I could not notice any differences between this pin and my other Blackhawk's (Bisley style in 357 also) pin, the base pin latch were identical in spring tension/workings/length/ect., and I am in need of some recommendations as to what I can do to remedy this problem.
I don't have this gun as a collector item, as it has been modified by previous owners, so there are no issues with repairs that aren't kosher, so to speak....
