A genuine question which has been on my mind for some time now.
It's no secret the community here has its preference for certain holster makers - JMCK, CCC, etc. But what specifically sets these holsters apart?
Vague terms like craftsmanship get thrown around, but what specific qualities make the PF-endorsed guys more desirable than the dime-a-dozen kydex benders out there? For instance, we all know anybody making a zero-cant kydex holster tries to pass it off as viable for AIWB, even more so now when they throw a claw on to it.
I'm interested in the experiences and observations of the community to help articulate why these holsters are superior to the rest.
I also welcome information on failures of competitor products during training (brands can be withheld if necessary).
