Rsmc optic cut is flat with no optic recoil support studs - TRYBE Defense Glock 43/43X Pistol Slide Version 2

This slide is nice unless you plan on installing a Holosun optic! I had a terrible time trying to mount a 2 different Holosun 507k optics to it! The optic cut for the slide doesn't have any kind of protruding studs that mate with the impressions in the bottom of the optic to help maintain zero due to recoil. When I bolt down the optic since the holes are countersunk you can't hold it straight & simply tighten the screws because the countersunk holes pull it straight with the poorly drilled holes!The optics reticle is visibly off to the left roughly 12 inches over 10 feet & there doesn't seem to be any way to fix it that I am aware of!
