Take whatever you can find, the dash number means nothing when it comes to shooting quality. All engineering changes are made for one of two reasons, simplifying production/cost cutting and improving durability, nothing more.

Shootability from an accuracy standpoint is strictly how well an individual gun matches up to the ideal combination of parts and how they relate to each other. Differences of less than .001" can make the difference between a tack-driver and a gun that won't shoot in a bucket. The reality is quality revolvers in general, as a rule shoot far better than they have any right to, and far better than most shooters are capable, even very good ones!
