Glock [G17 G19 G26 & other] front sight | fiber optic - Ubitzu

Sights for Glock 21

(24 products)

Iron sights for the Glock 21. Each set is machined for the Glock 21 slide cut, so it seats in the correct dovetail without modification.

Choose the piece you need – a front sight, a rear sight, or a full set – and the height profile: standard, low-profile, or co-witness to align with a slide-mounted red dot.

Co-witness height lines up with an optic, not on its own; pick it only if you run a red dot on the Glock 21.
