+1 for FIST, mine cost about $35-40 for the G27.
I also am very impressed my Comp-Tac MTAC,it is very adjustable, conceals better than any other holster I have, nothing but praises for it. And they deliver well under their shipping estimate almost without fail. Cost is $80, so it isn't the cheapest holster out there, but it is tuckable, the belt loops are set off from the holster body and have five adjustment holes each, for a total of ten different ways to set your holster, it is tuckable, and you can buy new half-shells for other guns for $35 each if you want to use it for another gun later.
I have bought a lot of holsters this year, and the MTAC and FIST holsters are by far my favorites. The low-end ultra-thin kydex FIST holsters I think are unbeatable for the price.
