Contender,
that's a G30 with Aero-Tek ghost ring sights and a laser-max and that's a new (for me) Comp-Tac shirt-tucker holster that I've been pleasantly surprised by. That G30 just disappears under a polo/golf type shirt, haven't tried a tee shirt yet.
Marc, while we are on the subject of Glocks, do you know anything about the glock Tenniffer finsh they put on their metal? That stuff is INCREDIBLE it doesn't come off and it NEVER rusts. That G30 has been COVERED in sweat for half a day or more during carry and it is still perfect. It has really blown my mind. Is the Tenniffer a Glock proprietary thing or what, it would be AWESOME on knives. I'd be interested in what you know about it.
