Hawg- no its on the cylinder face where the hand rotates it. Bolt seems to left very little wear on the old cylinder. Nothing on the new one.
Mykeal- the problem is only that the metal on the cylinder seems get worn quickly. The gun does lock up nicely.
Doc- anything that helps with learning is worth reading. Thanks for the suggestion.

I will read the links you guys have offered. Let you know.

Thanks everyone for your responses.
