I've had an IWB Blade-Tech for a Kel-Tec P11 for many years now. I find it comfortable and easy to draw from. Holsters, though, are about the toughest item to buy since there is no one source for trying the vast array of holsters out. About all you can do is ask for opinions and pay your money and take your chances!
I have one for my N frame and happy with it so far, and as posted above very good customer service. I wanted to remove the DOH feature of mine and it turns out the allen screws were somewhat tight/locktited in place. I called them and they sent another entire DOH unit with all the screws - I got it in less than 48 h.
