I can give a personal Thumbs Up to the Alien Gear Tuck 3.0. I ordered it on a Thursday, it was here the following Monday. I got the IWB, and it's just so comfortable. I was carrying my shield in it today, and so far every day that I've used it, it's getting more and more comfortable.

I nearly forget it's there. I can sit down in a chair, drive, and it feels great.

I would recommend, at least IMO, to try the metal clips rather than the standard clips they recommend. For me I think they will slide onto the belt better and easier. They should be here in the next few days so if anyone is curious I'll take some pics and let you know how it works out.
