I recently purchased a Colt Agent 38 special. The gun was only $200, so I couldn't pass it up. The gun was made in 1974 and has some decent holster wear and some light rust. While in the store an older gentleman told me he was a Colt collector and this was a fair deal, the gun just felt a little tight like it needed a good cleaning. He also mentioned that if I got the gun reblued, it would add to its value. I'll pry keep the gun since it's my first revolver and it's a Colt. Any input?
