These Trijicon Fiber Sight Sets are purpose-built as an upgrade to Glock's popular G42 and G43 concealed-carry pistols. They provide a fast, durable and easily seen sighting system that aids shooters in getting on target quickly in any self-defense situation. Each Trijicon Fiber Sight Set is precisely cut to fit the dovetails found on Glock G42 and G43 pistol slides and brings the same level of toughness and durability found in the company's other sighting systems to the world of fiber-optic sights.
