Could be better - GBRS Group x Priority 1 OWB Belt Holster

I got the Glock 17 with X300 version, this thing is TIIIIGHT, I undid the screws to almost all the way out so the kydex can open enough so it’s not in there with such strong retention. Since there’s no force being applied to the rubber grommet the screws are kind of loose, I guess I can take the heat gun to it all over while the gun is in there to loosen it up a bit, but should I have to do that? Compared it to my TREX Ragnarok and the kydex is a lot thinner, it did come with a belt paddle, the one you don’t need to remove your belt to put the holster on.
