Direct-fit red dots for Glock 43X MOS

In this category you can find all red dots that bolt directly onto the factory MOS cut of the Glock 43X MOS. No adapter plates, no dovetail mounts – the optic sits straight on the slide for a simple, compact setup.

These direct-fit red dots are chosen specifically for the slimline MOS pattern used on the Glock 43X MOS, giving you a micro optic that follows the lines of the pistol and keeps the sight axis as low as possible above the bore.

The 43X MOS is built for concealed carry, and a direct-fit red dot with an RMSc-style footprint is the most straightforward way to add an optic without adding unnecessary height or bulk.

Why choose a direct-fit red dot for Glock 43X MOS?

• Very low profile on the slide for a natural, repeatable presentation from concealment
• Fewer mounting parts between slide and optic for better durability and zero retention
• Slim, snag-resistant configuration ideal for EDC holsters and under-clothing carry

How to choose the right optic

When selecting a red dot, make sure it is listed as compatible with the Glock 43X MOS or with the slimline RMSc-type footprint. All models in this category are selected for direct-fit use on the Glock 43X MOS, so no additional MOS adapter plates are required.
