There have been a few threads lately asking about the size differences of various frames. Thought it might be interesting to put up a couple of pics that show various frame sizes.

Comparison of N to M.
Cylinder and cylinder window comparison of I frame and J Frame.
No matter the frame size, I am always amazed at the craftsmanship of the older S&W Hand Ejectors.
