Sorry, I figured that with the thread title being what it is it would be sort of a given. Yes, it is a 2 1/2 inch barrel. I seem to remember a thread here at the forum a few years back where people were showing their 2 1/2 inch barrel Model 19s and there was quite a few 2 1/2 inch 19-3s that had the TT, TS, RR and WO combination, I wonder if S&W simply had a surplus of the Target Triggers and Target Hammers on hand.

Oh, and I forgot to mention, my 19-3 also has the trigger stop.
