I just recieved an Officers Model .38 special, production date 1920. Gun is a shooter as it's been reblued. Now about the safety thing. I checked lock-up and cylinder tightnest, both good. Gun wouldn't chamber .38 S&W, so I used .38 special for test fire. Clicked three rounds DA, three rounds SA. When I went to release the cylinder, it opened without me unlatching it. I unloaded it, closed the cylinder, and it seems like it doesn't want to lock closed. It'll stay closed if I keep pressure on the release latch. Hammer cocked, cylinder stays locked in frame. Shot six more rounds, no problem. Pushed on cylinder without touching release, and it opened. I realize this is a problem, but how big a problem? Thanks for the help.
