I have their IWB for a full size 1911 and it rocks. It is ultra comfortable and is very similar to the Tucker "Answer" but currently only $36 deliverred. Turn around is fast and they are very accomodating. You can even tuck the thing.
It uses two Kydex clips to hold the gun in place and I have used both 1 1/4" men's dress belts made out of good leather and heavy 1 3/4" work belts with no problems. I can't rate this rig high enough for the price. It is easily worth double the current price. Grab one while the sale lasts.
