    Wanted something decent but not too expensive for my G3C . This sight is perfect for an EDC sub compact. Nice size with no overlap on the sides. I still love my Holosun better but it does hang over the sides of my G3 due to its width. The sightmnark is the exact width of my G3C and has a low profile for AIWB. Only issue for me is that the red dot is hard to see if you use a light against a white background . Probably due to the auto focus. Apart from that its an awesome little sight.
