I have seen you hint at the idea that current production K and L frame revolvers actually use the same frame.
I don't know, but I wonder. Doesn't it seem the K-frame has grown a little larger in recent years? Checking hammers is a good idea. The frame window and cylinder widths could also be measured.
The older K & L-frames had obvious differences. It was blatant. Newer one, say in the last five years or so, the differences are more subtle. From a manufacturing stand point, I imagine there would be significant savings by standardizing on one common frame size.
