i am looking for an enterprising fellow to help me find the perfect holster for my gun. i really like the retention method of the 5.11 tactical thumbdrive, but i was curious if the sight channel would accommodate my suppressor height sights which are ameriglo gl-429 "tall black set for suppressor use (item GL-404 + GST-315)Flat Black rear (.394”) and serrated front .315” x .090”" i have emailed 5.11 with my question and plan to post their response here. i am also waiting on the trijicon mos screw kit to arrive. i placed my order through opticsplanet. When i called trijicon to inquire as to when the part would become available again they said they should have screws of the correct thread and height tolerances delivered to them in about a month's time.
