Interesting thing about leather vs kydex. I LOVE leather holsters, but before I traded my XD9sc, I noticed it was starting to show a little holster wear on the left side of the slide, up by the muzzle, but none noticeable on the right. I carried quite frequently in the Kholster, and practiced quite a bit with the draw from it. The left side is the leather side. Reckon leather puts a bit more wear on the gun than Kydex?
Yep. Unless you let grit accumulate in the kydex, of course. Kydex is simple and easy to clean. Once grit gets embedded in the leather, it's there to stay.
kydex without reservation
- unaffected by moisture
- no break-in required
- adjustable tension
- won't loosen and fail to retain the gun over time
- stiff enough to reholster one-handed without issues; leather needs a steel reinforcement to have the same facility, which is heavy
- quicker draw stroke
- front sight won't get caught and impede draw
- can be made thinner/less bulky than comparable leather holster
- usually less expensive than a comparable leather holster
- easy to clean
This ^^^I have a kydex/leather holster (Crossbreed Supertuck). The leather feels better IWB, and the kydex has good retention (adjusted with heat) on the pistol; best of both worlds IMHO. Comptac MTAC, Kholster, and Crossbreed all use a kydex/leather configuration with adjustable cant.
I don't have any experience with strictly leather or kydex IWB holsters.
