Is there an option for "All of the Above"? Each is slightly different in its own way. I'm far from an early adopter (um, I STILL shoot revolvers, OK?), so out of the three it would have to be the model 66. Although, the barrel length is new, the actual dash-8 design has been around since 2014. I figure the bugs if any have been worked out by now. Actually, my first purchase will probably be the model 69 in the 2.75" barrel because I've never owned anything remotely like it.

Next will probably be the Colt if the trigger turns out to be similar to the Python or even the Detective Special. The Kimber is last for a couple of reasons. First, it is the most expensive (though the S&W 66 is close). Secondly, for a belt gun, I prefer an exposed hammer. And the Kimber, at 23 oz, is a tad heavy for pocket carry in my experience; YMMV.

These guns plus some interesting offerings from Ruger leads me to believe we are entering a Revolver Renaissance. And that's a good thing.
