I beg to differ - -
With all due resect,
texmex, the first examples of what we call the Chiefs Special were indeed made up on the I frame. Yes, the frame was nominally too short to hold the .38 Special cylinder, but, hey, what's the use of having your own gun factory if you're not able to make some variations?
The two I frame Chiefs I've handled both had four digit serial numbers. One had pristine, original factory stocks, and the other had J frame stocks which had been modified. That was what first drew my attention to the fact it was a non-standard Chiefs Spl. Another side note: I found a pair of really nice ivory stocks for a small RB S&W in a shop once and immediately began to deal on what was a very reasonable price. Luckily for me, the dealer was a casual acquaintance, and an up-front guy. Before any money changed hands he informed me the ivories were for an I frame and wouldn't fit on my regular pre M36 J frame Chief. I thanked him for preventing me from acquiring a white elephant [tooth.]
Granted, it was not long at all before S&W decided the I frame was a bit light for the .38 Spl, especially certain loads. At the time, there was still a lot of .38/44 and .38 High Speed ammo being produced, loads which make modern +P seem a bit anemic.
Sir William, I'd feel comfortable in shooting all standard (non-+P) .38 Special ammo in an I frame. If it wasn't my primary carry piece, though, I might prefer the 130 FMJRN "Air Force" load or regular 148 gr. full wadcutter target ammo over the 158 LRN. That small, short handle sort of squirms around with the standard ammo.
I don't have my
Standard Catalog of Smith & Wesson at hand, so I have no idea how many I frame Chiefs were produced, but it wasn't a large number. You have a nice little piece of transitional firearms history there, sir. Enjoy.
