You can ignore the non-S&W if you wish.
I noticed my M10 4" is getting a wear spot on the end of the barrel. Not sure how I feel about that. One of the reasons I bought it was because it was in mint condition. But she's been a good one on the range. I certainly have more rounds through her than the rest of them. (probably more than the rest combined.)
