    I was wondering if a 6 shots 686 can be changed to a 7 shot (or visa versa) simply by changing to a 7 shot cylinder or is there serious gunsmithing that has to take place? I see 7 shot cylinders for sale and wonder what it would entail to switch them out? Any competent 'smiths out there who could enlighten me? Thanks.

    I am not sure that it can be done because of the timing differences.

    There would certainly be some serious 'smithing needed. The 7 shot cylinder does not index around as far so the hand at the very least would require changing. I'm also pretty sure that where the hand attackes to the internals would need to change too since on my 6 shot S&W's the hand is fixed. There's no spring over ride to take up the excess travel of a 6 shot action to accomadate a 7 shot.

    So if you were to get this done it would be more or less a one way trip involving at least a couple of new parts installed and tuned under the side cover. This is assuming that the frame is the same for both.

    Yes, it can be done and it is not a big deal, though I can't recall all the details. Check the S&W forum, there are several threads there posted by folks that have done it.

    You need a new hand and cylinder. but it is best if you get the whole cylinder assembly or at least these parts

    I sent my pretty much useless* 7 shot to S&W and had it converted to 6. I am sure you can go the other way.

    *Useless to me in competition. There was a short while that a high capacity revolver was good in USPSA but they went to a six shot limitation, as does IDPA.

    Useless in IDPA, yes, as you can only load six. You have to take time to carefully index the cylinder as you close it, on the move, in the dark, under time.

    In USPSA you can load it up, but can only shoot six.
