Thanks EK... Good info, and dovetails with the revolver being made in the 1970s.
Couple of other notes...
The grips on these, while similar are not the same. The bottom edge of the grips on the M10 are radiused, and more comfortable in the hand. I've owned a fair few S&W k frames but never noticed any difference before.
I'll probably have after market grips on both of them soon enough
The ejector rod on the Model 18 needs to be loc-tited. I'll likely get it done this week, but in dis-assembling it I noticed that the revolver is significantly magnetized. Any ideas how or why this came to be?
