This may have been covered many times but it wont let me do a search. I have an OM SS with only a LR cylinder. It has not been converted and I really don't want to send it to Ruger because I figure when it comes back it would be. I want to buy a mag cylinder and my LR cylinder measures 1.64". Steve Ruger has some for sale but they only measure 1.62". Will the shorter cylinder work in my gun? I have been told there are also different size ratchet teeth. Will this make a difference? Or do I need to get one to match the pawl in my gun? Thanks in advance for all the Ruger knowledge imparted. Fom
