    Does machining a revolver cylinder for moon clips require the cylinder to be heat-treated again? The reason I ask is that I was discussing it with someone from S&W customer service and they believed it did and would even require a new cylinder. I know TK will do it to existing cylinders, but I didn't think heat treat was part of the process. It seems to me that machining it wouldn't ruin the temper like welding.

    I am not a metallurgist but I do believe that "heat treat" is not the same as "caseharden."

    TK and Pinnacle don't heat treat cylinders that they have cut for clips and they seem to do OK.
    I think you got somebody at Smith who was determined to make any aftermarket modification sound difficult. Void your guarantee, etc.

    No, it does not need to be heat treated again. The guy from the S&W CS told you some big BS.

    ^^^ What they said. No re-heat treat required.

    Mizar has it right.

    Heat treated steels are harden throughout the whole mass, not just the surface like case hardening and other surface treatments.
