opinions on turn ring

bedwards · Jun 3, 2025

Tempted to pick up this Cimarron (Pieatta) Frontier in 357 mag. It looks fantastic except for a prominent turn ring. I examined it closely and I don't see what caused it. Maybe something got caught between the frame and cylinder? Or a bur on the cylinder stop that is gone now?
Anyhow any opinions would be appreciated.

A properly made Colt’s will not exhibit this condition. That pistol is not properly tuned.

Frankly, it looks awful and would bother me every time I looked at it.

Impossible to tell from the picture but the tip of the stop is not what made the turn line?

I couldn't deal with a line so far off of the notch and ramp. I don't see how the stop could even lock in the notch if it is what caused the line.

That's what I don't understand. The ring is not in line with the cylinder stop as far as I can tell.

One cause, or so I've read, of turn rings is the failure of the operator to always fully cock the revolver before lowering the hammer all the way down. Lowering the hammer from a half cock position permits the bolt to rise and score the cylinder. Scoring or battering of the notches is likely a timing issue.

The notches look like new.

If you look close, you can see the turn line where it's supposed to be.

The other is a pass, no deal.

Ok thanks for the opinion!

I always follow this. NO lines on my single actions. I always inform anyone handling my revolvers.

I called the Cimarron customer service and that's what they said. I guess when a used gun is in a store, you can't control how it is handled.

I agree that that doesn’t seem to be a turn line as it is not in alignment with the notches.
As for no lines on single actions. ?
Colts and a Ruger.

Turn lines on a revolver that has been cocked are unavoidable [.]

Well, I know why its got the turn ring where it is now. And yes I bought it. (not at the list price) The PO must have taken the cylinder out and not made sure the base pin was back in the right place. There are 2 notches in the base pin. There is a spring loaded base pin latch nut that holds it in . The first notch is where you normally have it and the second notch will keep the hammer from going all the way down as a form of safety. The PO obviously had the base pin turned 45 degress. If you shoot it this way the base pin will walk out as it is not held by the base pin latch. If you shoot it enough it will walk out enough to allow the cylinder to rub on the frame. When assembled correctly the gun is timed right and is very tight. I don't think it has been shot much at all.
I cleaned it and warmed the cylinder with a heat gun, applied a little cold blue on the hot cylinder and its acceptable as a shooter.
thanks again for the opinions!

That right there. Operator error.

What a goofy lawyer-inspired arrangement that sounds like! As long as you’re happy…

Cylinder line on a Colt Single Action style
revolver was not handled correctly.

People cocking a S.A. are not bringing the
hammer all the way back to full cock anytime
it is actuated.

If hammer is ever put on safety half court cock
always take the hammer to full cock and gently
forward to take off the safety notch.

The best to you and your endeavors.
