Quick installation. good alternative fiber optic sight to stock sight options - Hiviz GL2014 Fiber Optic Front Sight for Glock

The sight was installed on a Glock 17 with Hi-Viz's sight tool. The sight is stable and functions well. Recommend using blue Loctite during installation as the instructions suggest. The sight picture is good and additional light tubes are provided in different colors. I did not install Hi-Viz rear sights and currently use the Glock stock rear sights with the Hi-Viz front sight. At some point, I will consider a blacked out serrated, metal rear sight to replace the stock Glock rear sight. I chose green for this application, but often use red for other pistols. Light transmission is good for daylight applications. It hinders a bit during nighttime applications (since it is not a night sight and I would not expect it to perform that way), but does catch light from flashlights and ambient light when available.
