As I understand it...Tom C had it done under warranty due to flame-cutting. I called Smith and they told me they would do it for $140 at that time....around 6-months ago. It was a "stage" I was going through concerned about the aluminum cylinder, of which...I am no longer concerned. I have two 317's that work like a Swiss watch and are both as accurate as I am at reasonable distances.

Contact Smith and see what they say. If they can't make it shoot straight, they may do it under warranty. If they can't prove you're not the original owner (if you are not)....they have no choice but to take it under warranty.
