I like uncle Mike's, I've heard good things about alien gear
If you're willing to invest in something that will outlast you, provide excellent concealment, and do all that with great comfort, I'd recommend a horsehide Kramer IWB (I'm the happy owner of their IWB#2).
It'll set you back right at the $150 range and takes about six to eight weeks to come in because they make them one at a time for a perfect fit, but this holster convinced me that a major reason why so many folks believe they can't comfortably carry full size sidearms is because they used a crappy carry rig.
I used to buy Fobus until I found out what a really good holster feels like. I can't carry in a Fobus for any length of time now that I know a holster does not have to feel bad while carrying. The Fobus mag holster was some of the worst money I've spent. It's simply painful to use.Can't go wrong with a cheap fobus imo.
You can guess the age of a shooter by how big his old holster box is. I am not kidding. I have a couple cowhides in totes. I don't know what animal kydex comes from.....But at least one has sacrificed it's life for me too...
