I have two. Horsehide is a very strong, thin, durable leather. The belt loops come in interchangable sizes to fit different belt widths. The loops are mounted to the holster using screws. They then use snaps to attach the holster to the belt. The mouth of the holster is reinforced, allowing one handed re-holstering.
One piece of advice. Break in the holster before using it to carry. On mine the initial fit was very tight.
While there are other good IWB holsters out there, I've been pleased with my Royal Guards.

BTW, if you are going to carry inside the waist band I strongly recommend that you buy your pants two inches oversize in the waist to allow room for the gun/holster. Trying to use them with your normal pant size will make for a tight, uncomfortable experience.
