I finally got a Springfield tech to give me the ok on +P+ in my XDSC 9mm. (I've been using it anyway). Just nice to have a corporate sanction (such as it is). I know I know, "It won't perform significantly better than standard or +P and it increases wear and tear" She didn't say anything like that other than the pistol will act differently because of the shortened slide. I don't care! :) I'm pleased with the results so far.
