My dad handed me a Colt Trooper .357 and it is gummed up pretty bad with some sort of grease. Is there a gunsmith in the Denham Springs area that could take a look at it and give it a good cleaning? I am tempted to do it myself but the only hand guns I have worked on are my SIG's. I am not sure if I want to dive into this one in case I lose or break something.
