I've been doing a bunch of research on various (mainly) IWB holsters and can't decide between Kydex and Leather. After perusing some sites I went to the highnoon holster website and read their FAQ section. On it they mention some downsides to Kydex: 1) Noisy 2) Uncomfortable - they say something to the effect of we've never seen any Kydex shoes. 3) scratches gun as Kydex is a dust/dirt magnet. In favor of Kydex are claims that it forms better to the weapon (injection molded), won't stretch out over time, and actually scratches the weapon less than leather. I was hoping those with either (or both) types of holsters could comment on this.
