A am new to revolvers and had a questions about some wear showing up on my nib model 10 (which has had about 250 rounds through it). There is a small wear spot on the bottom of the frame under the cylinder, on the right side as I shoot the gun.

Also, the very front edge of the side of the cylinder is showing a thin wear line all the way round. Very narrow, but the blue is worn away.

Is all of this normal wear?

Thanks for your help.

the ring is normal,called turn ring,they will get that if you just rotate the cylinder don't know about the other without a picture of it.

A line at the cylinder stop notches would be normal, but I would call that the rear of the cylinder. I finally found a no-lock Centenial at a local Cabela's, and was shocked at the yoke to cylinder shaft clearance and endplay. This was a new gun, and you could visibly change the barrel gap. Only my worn out j-frames exhibit this much slop.
