Unless you're experienced at shooting DA revolvers, I'd stay away from any j-frame. I'm mostly a semi-auto guy (and of those, prefer SA triggers), but I own a few revolvers. I bought a j-frame with the intention of carrying it. The trigger must've been 20lbs -- it was laughably, wow, I can't believe they actually sell this thing bad. It functioned flawlessly, but I just couldn't shoot it well. It also was pretty snappy for what is a lower end cartridge (as a comparison, my little taurus 709 snaps a good deal less with 9mm+p).
Anyway, I got rid of it for a SP101 (since I already had a GP100 that I love). Wow, what a difference. Much better trigger, and it's actually comfortable to fire -- even with full bore .357. It's definitely a belt carry only gun, and requires a real gun belt, but with an iwb holster and my beltman belt, it disappears under a t-shirt. I think it has something to do with the curve of the grip or whatever, but the darn thing just doesn't print.
If you want to actually be able to enjoy shooting the thing, especially with .357, I say get a SP101.
Anyway, I have tried out the LCR. Fantastic trigger, soaks up recoil better. In fact, had I purchased a LCR instead of the j-frame (as I almost did), I'd still own it. If you want a pocketable revolver, it's the way to go. But I can't imagine what it would be like to fire .357 out of it. Would probably feel like slamming your hand in a car door ever time you take a shot.
