Stupid question from a first time revolver owner

Personally, I wouldn’t worry much about either issue but would keep and eye on them to see if things change over time.

If you contact Ruger I would definitely send photos.

Welcome to THR.

I will buck the trends and say the groove in the crane looks like a casting flaw/crack to me. It's not immediately fatal to the part but that one would bother me. It could very well develop into a crack under hard use. If that was on a well used revolver I would be tempted to let is slide but on a brand new gun that seems like poor QC to me.

Aside from EXACTLY where it is, to me, it looks deliberate like a *witness mark*, inspection stamp, Rockwell test or the like.
Though I am all but certain it is NOT the case.... EXACTLY where it is would present as a clearance peen. Though, as I said, I'm certain that that is NOT the case.

Generally, I wouldn't worry about it as long as the bore beside it is perfect - as it likely is.

The crane however - with its potential crack - would have me returning it to Customer Service and as long as that was happening, I'd highlight the peen mark on the cylinder as well.

My initial impression was that it was a mark from a Rockwell test of the chamber mouth. The ugliness on the crane could be a casting flaw, or it could be a crack. If it were me, I would check on it for a while and if it doesn't change, no big deal.

Now THAT gets my attention. Definitely worth looking into.

Been a wheel gun fan for 40 years. I have them from a tiny NAA to several .44mags.

This site is pretty mellow. You even got welcomed.

If you'd been on one of the old rock climbing sites you would not have gone an hour without somebody screaming at you "yer gonna die!"

A little trick to try; load one magnum and five .38spl and spin the cylinder so you don't know where the magnum is. This will teach you the value of not flinching.

Mailed them the pictures this morning and asked to confirm the receipt. No response so far.

Ruger will take care of you. Their CS is outstanding. The cylinder "zit" I wouldn't worry about, not so sure about the gouge in the crane. I usually try not to look this closely at my GPs after I accept them but out of curiosity I looked and this is what my blued and stainless GP's cranes look like. A little rough but no gouges.

Looks like a hardness check to me... No problem. At least you will know the metal is in spec.

I am totally certain Ruger will make everything right for you if you ask them. The first ding you mentioned was hardly worth the time you'd be without your revolver while Ruger fixed it, but as you find more things, it becomes more compelling to send it away for a while to have them fixed. They should replace the cylinder and the crane. I still recommend getting some feeler guages -- the flat metal leaves that are commonly used to check spark plug gaps (and points if anyone remembers those) --- and see what is the fattest one you can slide between the cylinder and the barrel. 0.004" is about ideal, but factory production tends to be looser and you might have to accept 0.008" which is not bad at all. My experience with both Ruger and S&W lately is there might be as much as a 50/50 chance the gap is over 0.01". If it's bad, tell them to fix it. As long as it's going back to Ruger, you might as well get everything fixed. Check the muzzle crown for dings too. Check the screws aren't mangled. Check the timing, and check how tightly the cylinder locks up. Here are some good revolver check instructions: https://thefiringline.com/forums/showthread.php?t=57816

Agree. The cylinder issue is likely a nonissue. The crane bothers me.

I hope Ruger replaces both.

The cylinder ding would annoy me , but concern me.
The crane fissure would have me on the phone to Ruger requesting a shipping label.
As others have said , Ruger CS is first rate. (as I think you will be finding out for yourself soon...)

Cylinder
Crane that looks like a casting flaw and cracked to me.

Also, follow the rough area on the crane to the right and then down to what the cylinder rotates on.... that looks like it was grinded on when it shouldn't have. It don't think it's a functional issue but worth noting to Ruger.

The crane issue I don't think I would live with that considering it looks more than just cosmetic to me.

Welcome to the world of Ruger revolver cylinder issues.

I don't look at my guns under magnification. Probably a good thing, and I don't have anything to worry about that isn't noticeable in how the guns shoot. I hesitate now with Ruger, because they are quick to replace a gun rather than mess with it, which means that any gunsmithing invested is gone.

I have learned not to completely clean cylinder faces on stainless guns. After all, you cannot do that on a blued gun, and they shoot fine.

Mine aren't beveled.

I checked about 6 of my revolvers last night, 4 of them Rugers and none had a bevel on the chamber mouth. Curiouser and curiouser?

Is that a Match Champion thing?

Doesn't look like anything to worry about. Same for carbon rings.

I also highly doubt it will cause any problems but if it keeps you up at night thinking about it I would just pay close attention to whether or not that chamber throws fliers compared to the others. If not great. If so I'm sure Ruger will fix you up in a hurry.

Okay, so I checked my second generation MC with adjustable sights, and it has beveled chambers front and back, moreso on the back but not on the ejector star. I had to really look close to see it on the front but don't recall if I had the throats done on the gun.
