Improved I frame Or... Baby J frame
Until Hondo decides to tell me I'm wrong....I'll continue to interpret his words correctly describing a Baby J frame being different than a J frame.
That shorter grip frame is still important.
I doubt he will though....I'm kinda making sense.
-I frame
-Improved I frame (Baby J)
-J frame
^^^^^^all different frame sizes.

Leatherhead23,
The convoluted I and J frame evolution of the 1950s lacked research and correct documentation in the books for many years and that caused confusion.
There are three I frame variations and two frame sizes, (because 1 & 2 are the same size, just different mainsprings):
1. Pre war and Post war Transitional with leaf spring
2. Improved I with coil spring
3. Model 1953 NEW I frame forging
And 2 J frame size variations, but both have the same cyl window size:
Baby J
Model of 1953 NEW J frame forging
All vintages of J frames have an 1/8" longer cyl window than I frames, which determines them to be J frames. Neither trigger guard size nor grip frame length determine the frame size.
So there are two I and J frame grip frame sizes:
Pre model 1953 Transitional and Improved I frames, and Baby J frames have the same size grip frame lengths and grips interchange, (and same small trigger guards).
Model of 1953 NEW I frames and NEW J frames forging, again both have the same NEW 1/8" longer grip frame length, and larger egg shaped trigger guards. Since these grip frames are the same size, grips will also interchange.
I hope this is helpful,
