Ruger cylinder turning scratch mark

I think every Ruger I have ever seen had that scratch mark where the cylinder stop drags on the cylinder before engaging. Most revolvers seem to have this if they're cycled much at all. I admit, it bothers me. I have a colt navy reproduction with 500+ rounds through it and lots of non-firing cycling and it doesn't have a ring; the cylinder stop drops into the groove instead of dragging along the cylinder. I'd think that a Ruger, which is about 10 times more complicated internally than a colt navy, would be able to achieve a bit more precision here. Is it possible to tune the timing to solve this or am I just being too picky here? Or does the cylinder stop dragging on the cylinder have a purpose such as preventing the possibility of over travel and locking out of battery?

It CAN be fixed, but Ruger designs their guns that way intentionally....they want the early-rising bolt to make sure the weaker bolt spring has positively bedded the bolt in the cylinder notch when the hammer falls....your final statement hit it squarely...

Mtngunr nailed it perfectly.

Part of the design, yup.
Can it be fixed, yup.
Easily? Yup.
By a novice, Nope.
It's a Ruger, don't worry about it.

As noted, it is intentionally designed that way, and it also prevents cylinder throwby, which can occur in a typical Colt style SA design if someone starts pulling the hammer back rapidly and then slows before reaching lock-up.

On the older models---cock the hammer all the way and then pull the trigger and lower it. Never lower the hammer from half cock. This will stop the dreaded ring.

It's not just Ruger...EVERY used Ruger, Smith, Taurus, Colt, and other revolvers I've ever looked at have the ring.

A Colt in perfect time will not make the ring. Most revolvers are slightly out of time but still in spec. Just one of the pitfalls of mass production.

Hummm...Every revolver manufactured in the 19th, 20th and 21st century must be made out of time then as I have never seen a revolver that has been turned that didn't have the cylinder stop ring...

I look at it as a badge of honor on a revolver that it likes to be shot, and not just sit in a safe getting bored. :)

Count me as another one who's never seen a revolver that didn't have a cable tie around it, that didn't have a ring around the cylinder.

You mean like this OM Super Blackhawk? Like Majic said, it's all about timing.

Hmmmm..... :scrutiny: Unturned, huh?

No, I'd agree in theory about perfect timing being possible, but I don't recall ever seeing a revolver that got any use that didn't have the ring on it.

And that's after 46 years of shooting revolvers..... and counting....:neener:

The ring issue can be minimized by removing the pawl and polishing the surface that contacts the cylinder. I have done this on a couple and have not had a ring problem despite numerous range sessions.

No...Not unturned. If you look closely, jjohnson, you can see the turning ring...

Bushmaster is correct, there is a very slight turning ring. However, this revolver has been shot many, many times. Here is a link with some instructions on how to modify the action. There is also another link within with more information.

You can take a real fine black paper, taped on a ridgid surface and rub the sharpe, high edge that rides on the cylinder. At 1500 grit, no more then five or six passes. NO MORE or you'll reduce and detroy your part. If you look at the cylinder stop you'll see the right side of the parts is angled by a file and reduced on the right side by factory fitters. That highest point is what rides the cylinder and needs softening to stop etching that line. TOGGLELOCK

I've had Smiths, Tauruses and Llamas with these marks, too. Don't worry about it.

Oh, my eyes are old, but I'm not blind...:what:

No, I can see the faint ring. The comment was tongue un cheek about it being unturned.

I've never personally seen a revolver that had been fired that didn't have a ring. I'd have my doubts that it was properly fitted if I ever did. I'm sure it's possible, but I've simply never seen one.

I SHOOT my firearms like they were tools. I don't mistreat them at all, but I shoot enough that I've broken a sizable pile of gun parts that I never thought I'd see broken.

Next time you go to a gunshow, ask a dealer to look at a high end revolver (preferably unfired), spin the cylinder a few times and hand it back, he'll appreciate the fact you showed interest. To really make friends, take a nice Smith and close the cylinder by snapping your wrist.

Yup...That'll win friends every time.

jjohnson...Not a problem...Me too.
