Has my 14-3 been modified to take .357?

Very common to see N-frame original .38 Special revolvers with chambers lengthened to accept .357. I have one, from the mid-1950s, it handles .357 cartridges just fine. I have never seen a K-frame .38 Special revolver having lengthened chambers. Except the Model 19 which left the factory that way.

I had an acquaintance that reamed a Colt Diamondback to .357. I personally think he was a fool.

Leave Grandads gun alone and shoot .38 specials in it. Like it left the factory.

Note that the Colt .357, .357 Trooper, and original Cobra revolvers were essentially mechanically identical to the everyday Colt Official Police .38 Special revolvers but with deeper chambers and frame mounted firing pins.
