I have a 357 LCR - mainly so I have the option of either 357 or 38 spl - however, I rarely shoot 357. I got mine as i wanted a light weight CCW as opposed to carrying a semi-auto - I much prefer revolvers. That said . . .
I find it accurate enough for SD ranges. I have no problems hitting central mass with mine at 25 feet or so. Longer distances? I would imagine the pistol is more accurate than I am. I sometimes practice at longer distances but I probably wouldn't be "takin' home the bacon" in a turkey shoot with it. I've always shot SA - that said, with practice, I'm very comfortable with the DAO of the LCR - mine has a nice smooth trigger pull. It's lightweight and an easy - I carry on the belt. And I will add that I'm personally "plenty comfortable" with the 5 rounds for SD purposes. Hopefully, I'll never need it. If something occurs at a longer distance than I practice at, I should have plenty of time to turn and retreat and hopefully evade the situation.
If you aren't used to shooting a lightweight like the LCR - you accuracy may have been affected by a lot of things - anticipation of firing, you hold, a different trigger pull than yo are used to, etc. I'm not saying you aren't an accurate shooter and that the LCR may not have been "off" . . . I'm saying that if you fired a few hundred rounds out of it and got used to it, you may very well have done better.
I view snubbies as a up close SD weapon and I think you'd find that the LCR, the Bodyguard and similar lightweights would be very adequate for the closer SD ranges and that you'd have no problem with "central mass". Lets face it . . . regardless of how good a shooter a person is and if they can put all of them through the same hole . . the proof in the pudding is how well will they actually shoot in a SD situation when the adrenaline is pumping, you're scared to death and you have to react. I think the secret to the LCR . . . or any snubbie . . . is to practice, practice and then practice some more - "learn the gun" and then make you decision on if it's "accurate" or not. I've shot a lot of different pistols and very rarely did I shoot well with one right off the bat until I became familiar with it . . . which for me, usually takes a couple of boxes of cartridges.
Now that I'm used to my LCR . . . I'd be hard pressed to want to switch to a different snubbie . . . and I'd have no hesitation in buying another one.
