I bought too many Ruger revolvers, SA & DA, that had rough pawl channels, etc, and burr-filled drilled holes. I just knew that whatever new Ruger I bought, I would be the 'final inspector' - and 'adjuster'. My early .454 SRH was the closest to 'right'. I finally had enough - it was the .32 H&RM SP-101 and SSM with their oversized chambers that did it. Before then, I had bought one new Ruger - a 5.5" RH in .45 Colt - ordered locally along with a friend's similar example - that I couldn't fix and declared a 'return' choice. Mine had burst casting bubbles between the cylinder exit bores - not awe-inspiring for it's much heralded 'strength'.
I called Ruger - a toll call, BTW - they said, after getting that s/n, they wanted that one back - and sent a pre-paid label for it. My friend picked his up the next day - and it was back to NH within days of mine. My RH got another new cylinder, hammer, trigger, and internal parts - and a lightened trigger - for my troubles. On it's one month since purchase anniversary, I was shooting it at the range. My friend's had a warped frame - he got another new RH, which he promptly traded. That was 0 for 2 examples. Like me, he had a S&W 625MG in .45 Colt - and was spoiled. Mine worked, but I eventually sold it - after getting a second MG.
S&W has sent me an ejector rod and spring, gratis, over the years. They did send a pickup for my 4" 625-8, bought new 9/02, in 6/04. I had likely put 10k-11k+ rounds of ball ammo through it as my first SPC competition revolver. I often didn't tighten the yoke screw enough - it even fell out - along with the cylinder - twice. I found that screw in the gravel several times! The b/c gap was uneven and tight. I told S&W about my use - they said it was 'covered' - and sent a label. I had it back eight days later - perfect - gratis! I even sent them my blown-up (All my fault!) 629MG - in a body bag - and they, knowing I had only shot only my homebrews in it, sold me a new one for < half the best price I'd ever seen for one. My new UDR 2 5/8" PC627 recently came with poor-fitting Eagle boot grips - they sent a FEDEX Ground label for them! All of the S&W calls are via their 800#. Their trigger job quotes, etc, even include overrnite both ways - to/from your home. Good folks.
BTW, I have shot two different LCRs - with GA Arms +P 158gr LHPSWCs, ballistically equivalent to the similar Remingtons I 'carry' - just < half the price. I also shot 130gr MC plinkers. Both sounded and felt like they were 'coming apart' when they were fired - rattled empty. The +P's recoil was heavier than in the 642, too. The triggers were lighter than I remember my 642 being when it was new. My much-used 642 is now smoother - and maybe a teeny bit lighter - than the LCR, despite no trigger work or spring changes. IMHO, the 642 is an improvement over the LCR - and certainly worth a few bucks more. A 'new design' isn't always better. Of course, I divested myself or Ruger handguns - except for my BP c&b Old Army - so I am biased. Good luck with your LCR... I know a guy who replaced his old/worn out (from carrying!) 642 with one. I'll bet S&W would return his 642 to LN - he didn't know that!
