I recently recived a gift from my father in the form of a Ruger .357 "new model" blackhawk. He picked it up from a local pawnshop for 175 dollars. The thing is old, I was blued at one point but it's been reduced to a dull gun metal sheen. The small rod which secures the cartiage to the gun is only pushed about a third of the way in. When I compared it to pictures I found online, it struck me as odd. All the weapons pictured show this rod pushed all the way into the gun. I'm able to extend the rod out when the cartiage is ejected, but I can only push it in about an inch. I have no expierence with revolvers, and my father is in the same boat. We don't want to force it in for fear we'll break something. Does anyone have advice?
