About This Firearm
The Glock G35 Gen5 MOS is a long-slide striker-fired .40 S&W built for competition. Its slide leaves the factory cut for Glock's Modular Optic System, so a reflex sight bolts on through an adapter plate with no second slide and no mounting bracket above the breech.
Three magazines come in the box with the modular backstrap set, and the magazine catch reverses for a left-handed shooter. The optic cut takes the plate matched to whichever sight you pick, so the sight choice has to come before the plate order. The slide is nDLC-finished steel over a polymer frame with Glock's textured grip, and the trigger is the Safe Action with its blade in the face. Nothing else on the pistol adjusts.
If you're cross-shopping, the Glock G22 Gen5 is the duty-length gun in the same caliber, 15 rounds at 28.43 oz on a 4.49-inch barrel at 7.95 inches overall, and its slide has no optic cut at all. The Sig Sauer P320 holds 14 rounds on a 4.7-inch barrel at 8.0 inches overall with a 5.5-inch grip height, which is the closest thing here to a long-slide .40.

Strengths & Limitations
- One slide covers several reflex-sight footprints through the adapter plates, so changing optics does not mean changing slides.
- The polymer frame runs on hardened steel guides, so the slide rides on metal.
- Apart from the optic plate, every part on it is a stocked Glock item, so a match gun can be kept running from a shop shelf.
- A long slide and a .40 chambering make this a specialist pistol, longer and heavier than anything meant for carry.
- The adapter plate and the sight are both purchases on top of the gun.
- Nothing on the trigger adjusts, so a lighter competition break means aftermarket parts and the loss of a factory configuration.

Frequently Asked Questions
What does MOS mean?
Modular Optic System. The slide is cut at the factory and a set of adapter plates lets a reflex sight mount straight to it, without a new slide or a separate mounting system.
What does the long slide do for a .40?
It puts more distance between the sights and gives a longer barrel than a duty Glock, which is why Glock keeps the configuration in its competition line.
Is the grip the same as a duty Glock?
The frame uses Glock’s textured polymer with the modular backstrap system, so the same backstraps fit it.
