Glock G23 V MOS .40 S&W 4.02in Black

Description

The Glock G23 V MOS .40 S&W 4.02in Black is a Gen5 compact pistol built for shooters who want red-dot capability without giving up concealability. Chambered in .40 S&W, this MOS model comes with a precision-machined slide that accepts popular miniature reflex sights via adapter plates. The Safe Action trigger system delivers a consistent pull every time, and the nDLC finish resists corrosion better than previous Glock coatings. If you need a duty-ready handgun that can mount an optic straight from the box, this is it.

Key Features

• MOS Slide System — The slide is pre-machined with four mounting footprints so you can run a red dot without sending it to a gunsmith. That means faster target acquisition and better low-light performance right out of the box.
• Gen5 Safe Action Trigger — Glock’s three-safety trigger system gives you a consistent 5.5-pound pull with a short reset. Why it matters: you get predictable break and faster follow-up shots without training wheels.
• nDLC Slide Finish — The diamond-like carbon coating is harder than standard Tenifer, so holster wear and corrosion are less of a concern. Why it matters: your gun looks good longer and holds up to sweat, rain, and daily carry abuse.
• Ambidextrous Slide Stop — Gen5 adds slide stops on both sides. Why it matters: left-handed shooters get the same manipulation speed as righties, and it makes malfunction drills smoother for everyone.
• Modular Backstrap System — Three interchangeable backstraps let you adjust grip circumference. Why it matters: a proper fit means better recoil control and more consistent accuracy, especially with .40 S&W.

Who It’s For

This pistol is for the shooter who carries .40 S&W for its proven terminal performance and wants a compact frame that doubles as a nightstand gun. It fits law enforcement officers transitioning to red-dot sights, competitive shooters in limited divisions, and civilian carriers who prefer .40 over 9mm for barrier penetration. If you already own Glock 19 holsters and mag pouches, the G23 V MOS shares the same external dimensions — your gear still works.

Pros & Cons

• Pro: Factory MOS cut saves you $150–$200 in milling costs and keeps your warranty intact.
• Pro: .40 S&W delivers 10–15% more muzzle energy than 9mm +P loads, per FBI ballistic tests.
• Con: The MOS plate system adds a tiny bit of height over the slide, so suppressor-height sights are recommended for co-witnessing — factor that into your budget.

Comparison: Glock G23 V MOS vs. ZEV Technologies OZ9C vs. Agency Arms Syndicate

Feature	Glock G23 V MOS	ZEV Technologies OZ9C	Agency Arms Syndicate
Caliber	.40 S&W	9mm (9×19)	9mm (9×19)
Barrel Length	4.02 in	4.02 in	4.04 in
Optic Ready	MOS (4 plates)	Proprietary ZEV cut	RMR cut
Trigger Pull Weight	5.5 lb	4.5 lb	4.0 lb
MSRP	$648.96	$1,399	$1,895
Frame Material	Polymer	Polymer with stainless steel chassis	Aluminum

The G23 V MOS undercuts both competitors by at least $750 while still giving you a factory optic cut and proven Glock reliability. The ZEV and Agency guns offer lighter triggers and aluminum chassis, but you’re paying a premium for aftermarket customization. If .40 S&W is your caliber and budget matters, the Glock wins on value.

FAQ

What magazines does the Glock G23 V MOS use?

It uses standard Glock 23 Gen5 magazines in .40 S&W. Factory capacity is 13 rounds. Magazines from earlier Glock 23 generations are also compatible, though baseplates may differ slightly.

Can I mount a Trijicon RMR without an adapter plate?

No. The MOS system requires one of the included adapter plates to properly align the RMR’s screw holes and recoil bosses. Using the correct plate ensures the optic stays zeroed under recoil.

Does this pistol come with iron sights?

Yes. It ships with Glock’s standard polymer front and rear sights. Many shooters upgrade to steel suppressor-height sights for co-witness with a red dot, but the factory sights work fine out of the box.

Is the Gen5 G23 V MOS compatible with Gen4 holsters?

Yes, in most cases. The external dimensions are identical to the Gen4 G23, so any holster made for a Glock 23 Gen4 or Glock 19 Gen4 will fit. The only difference is the ambi slide stop, which may require a slight break-in on tight kydex holsters.
