I pulled my Smith out the other day and noticed stains, possible scratches. So I pulled out my cleaning kit and went to work. In the end I noticed about 5 mm scratches on the forward end of the cyl. So strange, when I look inside the gun I cant possible figure what it could rub to create them. I look top and bottom and ??? They are small diagonal marks, very faint. If dirt didn't get n them it would be tuff to see.

I am not talking the circle that goes all the way around the cylinder from rubbing. The other end of the cyl. I. cant load pics so...

Any ideas?
