Accessories for Glock

Glock is an Austrian maker of polymer striker fired pistols. Because the same basic design runs through the whole range, from the full size G17 to the Slimline G43X and G48, accessories for one model often fit several others. What decides the fit is the generation, the frame size and whether the slide is MOS.

MOS or classic slide

A MOS slide (Modular Optic System) has a factory optics cut closed by a cover plate. A classic slide has only the rear sight dovetail. This decides which sights and red dot parts you need.

Sights

Factory Glock sights are polymer, and they are usually the first thing owners replace. We have fiber optic sets for daylight, tritium sets from Night Fision and Angry Bear that glow in the dark, and adjustable LPA rears for setting the zero to your ammunition. If you run a dot on a MOS slide, co-witness sights give you a backup sight picture through the optic window. See Sights for Glock.

A red dot on a Glock

On a MOS slide, an optics ready plate replaces the cover and matches the footprint of your dot. We have plates in aluminium and steel from Toni System, KMR, 2BME, Eemann Tech, Holosun and Night Fision, for RMR, RMSc, Holosun K-series, DPP, Acro, RTS, Docter and EPS footprints. On a classic slide, the optic rides on a mount pressed into the rear sight dovetail, and the slide stays unmilled. For gen 4 frames there is also a frame mount that holds an RMR on the rail under the barrel. Plates are in Optics ready plates for Glock, dovetail and frame options in Red dot mounts for Glock.

Grip and reload

For gen 5 G17, G19, G19X, G34 and G45 frames, adhesive grips add friction with no tools, and aluminium magwells widen the opening so a magazine is guided in on a fast reload. Toni System base pads add from one to nine rounds on the full size magazines, with flat versions for the G19X, G43X and G48. The G17 and G19 frame families also take Toni System frame mounts, a block of aluminium or brass on the dust cover that holds the muzzle lower in recoil.

Frequently asked questions

How do I know if my Glock is MOS?

A MOS slide has a cover plate in front of the rear sight, held by screws, which comes off to fit a plate and optic. If there is only the rear sight in its dovetail, the slide is classic.

Do gen 4 and gen 5 parts swap?

Not always. Grips, magwells and frame mounts here are made for named generations and frames, as shown in the product title. Whatever the part, go by the models named on its product page.

Do I need a co-witness sight with a red dot?

Not necessarily, but co-witness sights let you aim with the iron sights through the optic window if the dot fails or the battery runs out. Standard height sights sit below the window and are hidden by the optic.

What if I order the wrong Glock part?

You have 14 days to return it. Write to info@ubitzu.eu before sending anything back; the part must be unused and as new, and you pay the return postage.
