I have two JM Custom kydex holsters. One was put through enough hell during two William Petty courses that any cheap kydex rig would have thrown in the towel day one. JM Custom are worth the extra cash. No idea if Haley is pushing JM, and generally don't care. What I do know is that quality will cost more and will last longer. As for AIWB sucking, well, no, no it doesn't. Not at all. Especially with a Glock. Full size 1911? Maybe, but a G19 in a good AIWB is a perfect combination.
