Are we just considering the -1, or does any 3.5" Model 27 qualify for consideration? Aside pure collecting, if one is going to shoot these guns, is there any reason to hold any variation in the progression of manufucature over another, as long as they are all 3.5" guns? Over the years, I have seen plenty of 3.5" guns here in Ohio, but they were usually dumped by cops for Model 19's in either 2.5" or 4", as those guns were lighter and handier to carry. I have also heard that the heavy cylinders of the N-frame .357's tended to wear at the cylinder notch more, as they induce more momentum and stress at the bolt/notch when cycled fast on DA. The early 27's were pretty guns, for sure, but did not meed the needs of the majority of shooters. Price, weight, and bulk made a lot of people choose other guns.
