I feel like I didnt say enough good about leather, so here's one other thing...Leather will break into your gun, Kydex doesnt move. So assuming the kydex holsteris well made...no problem, but if its a tad off...its going to be a tad off for a long long time.
Mad Dog makes good holsters...
As well as Edge Works, I know several people who have dealt with Edge works very succesfully, as well as a custom knife maker who has them do all of his sheaths now.
There are also other places out there...just a matter of who you like
