I believe the difference here is the fact the Model 17 is a rimfire vs. a centerfire. The rimfire, with a chamber which is still recessed, there is a slim chance of the firing pin striking the chamber rim, that can't happen with a centerfire.

Correct. It is not the frame mounting of the FP that makes the difference. It is the possibility of the FP striking the rim of the charge hole on the cylinder. That obviously cannot happen with the centerfire. It is not supposed to happen with the rimfire either because of the stop built into the FP, but I guess the tolerances can be such that it could occasionally happen, so S&W does not recommend it with the current guns.
