Thank you for the pics. Glock geometry is a lot different than your CZ or Sig. It sits lower in the holster and the front corner of the BROS rubs.
I’ve literally tried 3 of the most popular USPSA carry optics legal holsters for a Glock 17 (Comp-tac International, BladeTech Signature, and Ben Stoeger Unicorn. None of them fit without dremeling and why I started this thread.
I appreciate everyone’s input, but a lot of folks without direct experience are making assumptions.
