The Trijicon Fiber Sights for Glock MOS Small Frames set fits Glock 42, 43, 43x, 43X MOS, 48 and 48 MOS pistols, so it covers the MOS versions along with the standard small-frame models listed. It pairs a red fiber front sight with a black, non-illuminated rear, and the factory installs a .060" fiber on the front so the sight arrives with its fiber already in place. An extra red and green replacement fiber comes in the package, giving you a spare if you want to swap colors. The thin .110" front post gives a refined sight picture, and the bright front fiber against the subdued rear sight helps your eye find the front sight and the target.

The rear sight has a square-notch design and a steeply hooked front surface that assists with emergency one-handed slide manipulation. Rounded edges on the rear sight reduce snag points, which makes the set more comfortable to carry concealed. Trijicon builds the sights with rugged metal construction and fiber technology to maximize retention and durability through rough handling and aggressive holster use. Trijicon recommends professional installation for these sights.
