I have 3 super blackhawks and 1 of the pistols the cylinder pin will jump out when shooting the others don't have this problem. with the same loads. I can't figure it out the pin latches up fine or seems to you cant pull it out without releasing it. I took it down and there was a shiny spot where the latch goes on the top edge of the grove so I figured it wasn't seating right. So I took a round file and opened the grove a little so the latch would fit better but it still comes loose when shooting. With the cylinder removed everything seems fine you cant budge the pin with finger pressure without mashing the release. Is there something I'm missing. This gun is in great shape and hasn't been shot much at all. The pin will be out about 1/4" after each shot and will push back in easily and latch up seemingly fine but after each shot it is loose again. I have 10 ruger single actions and this is the only one that does this. What are your suggestions for a fix. I really don't want to return it for repairs to ruger if its a simple fix I can do.
