I just had mine delievered today. I ordered the horsehide model because I have an affinity for the animals.
I was a little skeptical of how exactly an IWB holster would feel, especially since I'm pushing around a little more weight than I'd like, but I have to tell you that I'm impressed as hell!
I'm carrying a full size M&P, and fully loaded this holster bears the weight, and distributes it so evenly, that it actually feels quite light. The unit is somewhat easy to put on, (I think this will get easier with time), and with my gun holstered, it rides very well at about the 3:30-4:00 position on my hip. I can see that this will be a very comfortable holster to wear all day.
The Kydex portion of the holster is molded like a glove to my M&P, and retention of my gun is absolutely spot-on!
Overall, I am very impressed with this holster. The comfort, fit, and finish, kind of make me wish I had held off on the OWB DeSantis holster I bought. (I'll probably still use that one too though).
