Hello everyone. I'm new to the forum and a new owner of a nickel Colt Python. The gun was made in 1978 and is in like-new condition. I'm trying to get an idea on what is safe to clean the nickel finish with. Is Hoppe's 9 OK? I use Hoppes and FP10 on my autos. I obviously don't want to tarnish the nickel finish but after a couple hundred rounds, it's ready for a good cleaning. Any recommendations would be greatly appreciated.
