Optics ready plates for Glock 27

The Glock 27 MOS is the subcompact .40 S&W Glock with the Modular Optic System. The factory cut accepts standard plates in common compact red dot footprints.

The reason to mount an optic on the Glock 27 is speed and consistency — a slide-level dot is faster to acquire than irons and stays in your sight picture as the gun cycles. The plate is the bridge: it mates the gun's mounting interface to your red dot's footprint and holds the optic low and rigid so point of aim does not wander.

Two dimensions have to line up — the cut or rail on the Glock 27 and the footprint of the optic you intend to run. A few plates include an integrated rear sight to preserve a co-witness backup. Check both against your setup on the individual product page before ordering.
