(CrashBomb @ Oct. 09 2006,21:53) I'm not sure about the ports on the XD but for a CCW piece that's going to be used primarily for defense, the whole "gas port" thing isn't always as great an idea as they first sound. Yes they do reduce recoil (well...muzzle flip at least) and theoretically that will provide a faster follow up shot, but think about this logically for a second, how fast is your second shot target re-acquisition going to be in the DARK (where most personal defense situations happen anyway) when you've just blinded yourself (and destroyed your night vision) with your own muzzle flash.
Just something to think about. I've never shot a ported XD, but I know the ports on the Glock C models really throw out some serious fire and it's BRIGHT in a dark room, you can see spots in front of your eyes after you shoot it. It's better to learn to controll the recoil with your wrist and practice faster double taps at the range than to rely on an element of design to do it for you.
