So a couple of three weeks back, I picked up an Interarms Rossi M971. I didn't have the luxury of shooting the gun first, it looked good though. The forcing cone looks great. It locked up tight, had my feeler gauge with me. It might need a good cleaning maybe. Here it is paired with an SP101 along with a shot of the forcing cone...

After getting it home, I loaded some snap caps and started working it a little. The action seems nice enough, but it wasn't long before I noticed that the cylinder would not always turn working the revolver on single-action. It doesn't happen very often, but it does occur on any given cylinder at random. Double-action is fine. Like I said though, it's not often. Yesterday I noticed the snap caps themselves were dinged on the edge, as if the hammer mounted firing pin hit the edges of two or three of them. They are not new snap caps...

At this point, I'm shopping for a gunsmith. Haven't fired it yet, mostly bought it for target practice. Most of my time dry-firing it, I was paying attention to see it locked up properly and never noticed anything irregular in that regard. Any thoughts from you revolver guys on the board?

Wow, never seen firing pin hits that far off center. Have you checked the timing yet? One of many videos describing how to check and resolve many timing issues:
. Take a look at the teeth on your cylinder star, For it to be that bad I gotta assume you are missing a few, or a few are damaged maybe,,just guessing here. But I bet it is timing. Kinda weird, since you already checked lock-up. Let us know what happens. I owned exact same model for a few years, no timing issues, and was a smooth running revolver. Accuracy was not a good as a Smith or Ruger, but cost half the price.

I can't be absolutely certain the firing pin on the Rossi caused those indents. There could be an issue with the cylinder star as it appears to have some uneven wear on the teeth. It's very hard to capture on a cell phone camera. The hand? Again, it's hard to tell, I haven't taken the side plate off yet. End shake? It doesn't seem any worse than the SP101. I've got a Rossi M68 out at the camp, and will compare it to the 971. Thanks.

Take the side plate off and clean and lube properly, looks to me like the cylinder stop is not going completely up
causing the cylinder to freewheel............................
I have this same firearm, and it is a great shooter!

troutkiller,
Where in the world did you find a set of metric screw drivers, they stopped making them years ago.

I also have this same firearm (4 inch), and it's one of the best .357's I own. Don't give up on the gun. I think I also had this happen on one of my (other) best revolvers when I first bought it - a '68 Colt Diamondback. A good cleaning and lube (as well as working the action a lot) and the problem went away pretty soon. After hundreds of rounds, the problem hasn't returned.
