Hi, I just bought a circa 1961 4" RB and plan to shoot a few rounds through it. However, on working the actions, I found out the cylinder release latch is a bit rough. Sometimes it binds and there is a bit of side play on the release latch. Since it is a 60 year old Python, I figured to send it to a good Colt gunsmith here to thoroughly clean and lube the internals and replace any parts deemed necessary. Can anyone recommend me a good Colt gunsmith here in the San Francisco Bay area ?
