It’s a good thing I haven’t used WD-40 on this gun yet. I did use some good gun oil for preserving purposes though. I’ve not shot it but just bought new rounds and kept the old ones in the box. They are much older than I thought but will stay there in their box. Thanks again guys. I know this isn’t the place for Ruger but wondered if anyone knew about a 52-53 model Blackhawk. I just bought it from my stepdad, as he let me buy many of his collection. He’s 90 and figured they were in better hands with me. I am so blessed to have what I have. God is good... All the time!
