Or take it to a comptetent smith.
Good on you for taking a lib shooting.
P.S. Buy an(other) autoloader. You have the extra money.... you know you want one.... And buy another wheelgun while you're at it.

I love that smell too-- it brings back a flood of nice memories of shooting with my Dad and friends as a teenager.
