Have you tried shooting without the extension? I've got an XD40 sub with both "sub" 9 round and a full size 12 round magazine with the sleeve to make it a full size grip. It's a bit more comfortable to shoot with the 12 round, but easier to carry with the 9, and no noticeable difference in speed or accuracy. There's also the Pierce grip extension-On the XD, it's just a pinky ledge, doesn't hold extra ammo.sgjr said:Seeking a decent, reliable 9mm or .40 sub compact with an extended magazine to allow for placement of little (pinky) finger for CC. Recommendations? What to avoid?
