Well, I happened to find an LCR at Ludco's Gun Shop in Parker City, IN yesterday and it followed me home. The fit and finish were much better than I expected and it just felt "right."
The trigger is different than my J-frame S&W's. It is just as light as my 642--the one with the most extensive trigger work--and much better than the others that have stock triggers. The LCR stages differently than the S&W's. I'm told that it feels more like the trigger on a Colt Cobra, but since I've never shot more than a few rounds through a Cobra it's hard for me to say. The first stage positions the cylinder and locks it in place and the second stage drops the internal hammer. Different from what I'm used to, but nice.
The sights are large but difficult to see against a dark background. In the future I may replace the pinned front sight sight with a high visibility dot sight when they become available. I'll also likely invest in the Crimson Trace laser grips when they become available separately.
Some articles have stated that the LCR will fit in holsters made for the the S&W J-frames, but that is only partly true. I have lots of snubby revolver holsters made for J-frames, and the LCR will fit in about 1/3 of them. The trigger guard is shaped differently and prevents fitting in the form-fit holsters.
Shooting the LCR surprised me. It surprised me a lot. I can normally shoot roughly 6 inch groups with my 642 at 7 yards...not great, but sufficient for my purposes. With the LCR my groups shrunk to about 3 inches with a variety of loads at the same distance. I don't know what to attribute this to, but I don't really care why it's happening, I'm just pleased that it is.
Once I can get the big dot front sight and the CT grips, the 642 will move to my safe and the LCR will be in my pocket.
