Do any of you guys own an "i frame" ? I've never seen one, but they sound interesting.
If you are referring to any "I" frame, then yes, I own several. If you are referring to an "I" frame Chief Special then I have to advise you that they do not exist.
The Chief Special was ONLY ever made on the "J" frame as the cylinder and the cylinder window were longer to accomodate the new longer .38 special cartridge. The butt and trigger guard of the early "J" frames were smaller and therefore collectors refer to these early guns as "Baby Chiefs". Since they are similar in size to the "I" frame, many folks confuse this fact and think that these early chiefs are "I" frames or improved "I" frames. That is not the case due to the enlarged frame window and they are only built on the "J" frame.
I hope that is what you were asking, if not please disregard my prior transmission.

Still looking for any 1 or 2 digit guns. Any new additions???
