I'm having trouble telling the improved I frame from the early J frame.
Someone who knows, tell me what I need to know.

An easy way to tell is to look at the curve between the forward trigger guard and the yoke. On the I frame, the curve is a short radius, whereas the J frame has a bit more length (towards front of the gun) to it. May be hard to envision, but once you have an I and a J side by side, it's easy to tell; then you'll never forget!
