I was very disappointed by one of these earlier this year, which is sad, because I really wanted to like it.
My experience with the LCR was pretty negative, very tight chambers that were difficult to extract (same ammo shot through two j-frames worked fine) and a trigger that was light, but had a vague and very long reset,which often caused me to short stroke. In addition, it's a bit bulky and although it's made largely of plastic, it isn't much lighter than all aluminum revolvers.
I put about 100 rounds through one this summer and went back to my J-frame. A heavier trigger, sure, but, no short stroking issues to train around.
