First of all, you guys have a really nice and informative site, I have enjoyed my time visiting here. I just bpicked up a 1991A1 Commander and from what I've learned here, I think it may have the "dimpled" barrel. Problem is, all of the links to pics I've found through the search function are too old and are no longer there. Can any one post a pic of what these newer barrels look like from the chamber end? Thanks for any info.
