STAGE 2--I can't say that I agree with you, but whatever the reason, the LCR does the job, and does it better than any of my J frames.
I have a 640 in .357 Mag, a 442 and a 642 in .38 Special, and a 940 in 9mm. The 640 and the 642 have been completely reworked and tuned with new Wolff springs, and the 640 has been ported. The trigger on the LCR is as good as the 640 and better than the 642 right out of the box, while both of the Smiths have had the $200 trigger jobs.
As for size, your point's made about the grips. The standard Hogue grips are larger than many of the grips made for J frames. They are also somewhat "sticky" for pocket carry. The Crimson Trace laser grips are much thinner, 1/2 an ounce lighter, and have polymer sides rather than rubber sides for better pocket carry. I would say they are very similar to the LG-405 grips made for the J frames, and which I have on my 442 and my 642.
Other than the grips, the only other part that is a bit larger is the trigger guard which I welcome since I have to sometimes qualify in cold weather when I'm wearing gloves. The cylinder is the thickest part of any revolver, and the cylinder on the LCR is actually about .02" slimmer than the cylinder on my 642. I may be wrong here, but I doubt very much that the groups I shoot with my LCR are half the size of the groups I shoot with my 642 just because the trigger guard is a little bigger. I tend to think it might be the better trigger, the better sights, and the overall better ergonomics of the LCR.
Since we're quoting the gun scribes, did you catch the review in GUN TESTS?
The LCR represents the first steps forward in revolver construction since the introduction of the modern eight-round revolvers. Few small revolvers, or pistols for that matter, provide the hand with the proper index for rapid repeat fire. That the LCR achieves this among other timely innovations is perhaps the biggest gain. The LCR in combination with the Black Hills 125-grain JHP rounds produced the only pleasing accuracy throughout our tests.
The LCR turned in the best groups for each of the shooters in the GUN TESTS team. Handguns tested were the LCR, the S&W 442, and the Charter Arms On Duty. Each were five shot .38 Special +P's weighing in at < 1 lb.
