Ruger SP101 weird cylinder lockup

What's up everyone. I got a new sp101 the other day, haven't shot it yet but I was doing a cylinder lock up test with the trigger pulled, 2-3 of the chambers lock up really tight. I know there's supposed to be a little wiggle, but some of these chambers like I said are real tight. I saw on another forum someone had a similar issue (but they were complaining some chambers were loose and the rest were "nice n tight")

I have not seen anywhere where anyone was spitting jacketing with their sp101 or having accuracy issues, but I was just wondering if anyone else has similar results.

Does your sp lock up tight on all chambers, proper wiggle on only some like mine or do they have a few degrees of freedom in all chambers?
 
UPDATE: I was messing with the lock up alignment and it looks like one of the looser cylinders natural resting positions is slightly off center. Now I'm still going to shoot it but I'm really OCD about this type of stuff so I'm going to mark that cylinder and if it gives me flyers it's going back to ruger.

How common is this in revolvers?
 
Sure, it should be a regular part of cleaning and inspecting any revolver.
Especially considering the effects if the lock up and timing are off.
The guy standing next to you at the range will thank you.
 
how "off" must they be to really start affecting accuracy or spitting jacketing

Not much.
Anything other than perfect alignment should be investigated.
But some guns can show slightly different degrees of lock up and timing depending on the speed of the trigger pull and cylinder rotation.
So check things by operating it just as it would be with live fire, both double and single action modes.
