My LCRx .38 is doing very well, bought it when it first hit the street. I never have keep up with round count on any of my firearms for some reason I never saw the point. I shoot them whenever i can and as many rounds as I have time for, if they brake, i get them fixed or replace them.

RugerFamily - ONLY out of curiosity – how is the lock up on your LCR when the trigger is pulled fully to the rear? Several normal people have told me that I am being anal when I am so concerned about loose lock up. They say that the slightly loose lock up allows the bullet to better center itself in the forcing cone ... I would say, and this is strictly a SWAG, that the inertia of the cylinder would prevent much in the line of rotational movement – to align itself – during the nano-second that the bullet needs to pass from the cylinder into the forcing cone…

Longterm Durability of LCR Aluminum Frames

It has a small amount of movement. I also noticed that the rear of the cylinder got dirty with powder residue, that does not happen to the GP... not gonna worry about it yet.

Testing lockup with the trigger pulled fully to the rear is NOT a valid Ruger test.
It's for older Colts & has no real bearing on Ruger DAs.

Actually, sorry. I checked and it doesn't move much at all. It's actually less then the GP.

As soon as I read this I went to get two examples and check them - my .22 LCR and most recent 2-inch SP-101. As I described before, the .22 LCR locks up tight - maybe not a bank-vault tight - but tight at full trigger pull. I had a chance to check two other (.38) LCR's in the past few weeks - and, sure enough, neither of them were tight a full trigger pull. I've owned SP-101's since late 1990 - currently have four .357's - all lock up tightly at full trigger pull.

So, if full trigger pull isn't a valid Ruger test - then I am at a loss to say what is a valid test. It may well be that a loosely-locked revolver is just as accurate as a tightly-locked one - I don't profess to be very knowledgeable on this, so I don't know. I can say this for sure: if I'm going to pay $400 to $700 or more - then I'm going to continue to reject DA revolvers - whether Ruger or S&W - that do not lock up tightly. Understand that Ruger SA's have a different ratchet setup and have never locked tightly in my experience - at least none of the few I have owned. But, this thread is about DA revolvers ... kinda-sorta ...

There is no valid lockup test for DA revolvers at home in the sense that you're talking about.
Note I said in the sense that you're talking about.

On older Colt V-Spring actions, the hand plays an instrumental part in full cylinder lockup by virtue of the way it engages the ratchet teeth.
That's what creates the old "Bank Vault Lockup" slogan.
That's what also causes the hand to be a more vulnerable part to wear.

With the trigger pulled fully to the rear on those actions, the hand serves two purposes: the hand advances the cylinder & the tip of the hand pushes strongly against the ratchet tooth in lockup.

On Smiths & Rugers, the hand typically serves one function- to advance the cylinder, and in the Smith hand & the Ruger pawl, neither is DESIGNED to push strongly against a ratchet tooth in lockup.

That's why in the Colt you adjust timing by lengthening the hand, and in the Smith (for example) you adjust timing by widening the hand.

You will find Rugers that will give you a tighter lockup with the trigger pulled fully, and you'll find Rugers that won't.
That's more a function of tolerance stacking than design.

Trying to test cylinder lockup on a Ruger DA tells you only that the gun in your hand at the moment does what that gun does in your hand at the moment.
You may pick up an identical one that may show tighter, looser, or same with its trigger fully back.

You can test for carry-up regarding timing on a Ruger, you can use a range rod to test for chamber alignment under lockup, you can use gauges to test headspace.

If you think it's got too much rotational play when locked, you can return to Ruger & have them see if that cylinder play's within their specs. I don't know how they determine that.

But- the "trigger test" is meaningless on a Ruger.

Denis - Great info - Thanks! Unfortunately, my income situation prevents me from getting out to the range any more often than once a month. So, I really can't speak with authority - as far as accuracy – on the whole tight lockup versus loose lockup subject. Bottom line, I was speculating and I hope I came across with some clarity on my lack of detailed and in-depth knowledge on the whole subject. Fortunately for all of us, there are folks like you and Iowegan, Wave, etc who are much more knowledgeable and willing to share your knowledge…

Rotational play under lockup can affect accuracy, if too extreme.

I returned a brand new Taurus .38 snub last year that had so much play it made both me & my gunsmith nervous about shooting it.

I emphasize EXTREME.
