So I liked the idea of getting a holster that would allow me to use my surefire x300 when I wanted and still holster the gun when its not in use. I needed a new holster as I got a deal on a PSA threaded barrel with a holosun 507 slide. I picked that holster up and drilled a hole in my QLS adapter for my safariland holster set up as the alien gear doesnt use the same pattern (only real complaint). I just went level 2, I dont need the extra retention for what I do. Holster has been great and its somewhat new so I don't see many people talking about it. Is anyone else running this holster? What comp are you able to fit on your glock 19 with this holster?
