Tapco Tritium Night Sight for Glock MOS Pistols

This Tapco tritium sight is made for Glock MOS pistols running a slide-mounted red dot, giving shooters a fast, always-visible backup reference for home defense, duty, or range use. It sits at optic height so it works with your red dot instead of fighting it, making it a smart pickup for anyone building out an MOS Glock with a reflex sight.

The sight uses a tritium insert that stays illuminated day or night, so there's no battery or activation switch to worry about. That tritium element is ringed with a daylight-fluorescing material for strong visibility in bright conditions, and the black frame is sized to obscure less of the optic window while still allowing three-dot alignment when needed.
