All you do is loosen the screw, adjust to where it is needed, and tighten the screw and now you have a different cant.
If you leave the screw slightly loose it will adjust to where it needs to be as your body moves
I've been using one with a Glock 23 in it for two years and it has held up great and been extremely comfortable.
I did buy one for a shield 45 and one for a Glock 17 and both of those styles ride higher than the Glock 23 for some reason. I get around it by using the Glock 17 in the 23 holster
