I've looked at my parts list, and from the different models, it shows MIM parts, etc. There is different part #'s for the different models of 45 cal. Maybe just the difference between MIM and forged parts. This is what I don't know, and could be interchangable.

So, I would call S&W parts dept. and ask them. i.e. if i were in your shoes, this is what I'd do.

Hope this helps
