I'm approx 6'1" 190 lbs, holster is for a Smith & Wesson M&P9C. Fits the gun perfectly, fits me good, easy draw, very secure and simple locking mechanism. Does not bite in the shoulder like many shoulder holsters.
Can be "somewhat" concealed under a t-shirt (M&P9C is not really a small gun). Allows easy and comfortable driving while armed.
It can be mounted for a vertical or horizontal draw, but because I have no gut it cannot be concealed when mounted horizontally. Requires 5 minutes with the included allen wrench to flip horiz/vert mountings.
Pros: Holds pistol very securely, easy draw, mostly adjustable, comfortable
Cons: Flops around a little bit
