Description

The Glock G23 V MOS .40 S&W 4.02in Optic-Ready Compact is a proven duty pistol upgraded for the modern shooter. It combines the trusted .40 S&W stopping power with Glock’s Modular Optic System (MOS), letting you mount a red dot sight without milling the slide. Out of the box, it includes three 13-round magazines, front slide serrations, and the factory Marksman Barrel. This is a serious tool for those who train with purpose.

Key Features

• Optic-Ready MOS Slide: The Modular Optic System allows direct mounting of miniature red dot sights using included adapter plates. Why it matters: Faster target acquisition and improved accuracy under stress — you keep both eyes open and focus on the threat, not the front sight.
• Glock Marksman Barrel (GMB): The 4.02-inch barrel features enhanced rifling and a recessed crown. Why it matters: Tighter shot groups at defensive distances — I’ve seen students cut groups in half just by switching to a GMB-equipped Glock.
• Front Slide Serrations: Aggressive serrations on the front of the slide give you a positive gripping surface. Why it matters: Press-checking or clearing a malfunction is easier with wet or gloved hands — no more fumbling when it counts.
• .40 S&W Chambering: The cartridge delivers more energy than 9mm with manageable recoil. Why it matters: Proven law enforcement round for decades — it penetrates barriers and expands reliably, giving you an edge in self-defense scenarios.
• Three 13-Round Magazines Included: Comes with three magazines for immediate range use or carry rotation. Why it matters: More training time and less downtime — you can run drills without constant reloading.

Who It’s For

This pistol is built for the shooter who trains seriously and wants an upgrade path. It’s ideal for concealed carriers who prefer .40 S&W for its terminal performance, competition shooters in Limited or Production divisions, and active-duty or retired LEOs who want a familiar platform with modern optics capability. New shooters will appreciate the consistent trigger and easy-to-learn manual of arms, but the MOS system really shines for those who already have red dot experience.

Pros & Cons

Pros:

How do I mount a red dot on the Glock G23 V MOS?

You remove the cover plate on the slide, select the correct MOS adapter plate for your optic (included with the pistol), and mount the optic using the provided screws. Torque to manufacturer specs — typically 15-18 in-lbs — and apply blue Loctite to prevent loosening.

Does the G23 V MOS come with suppressor-height sights?

No, it ships with standard-height Glock sights. You will need to install aftermarket suppressor-height sights (such as Ameriglo or Trijicon) if you want a lower co-witness with your red dot. Many shooters prefer this for backup aiming.

What holsters fit the Glock G23 V MOS?

Any holster designed for a Glock 23 Gen4 or Gen5 with an optic cut will work. The MOS slide is slightly wider at the optic pocket, so ensure the holster is molded for an optics-ready slide. Brands like Safariland, Alien Gear, and CrossBreed offer compatible options.

Is the .40 S&W still effective for self-defense?

Yes. According to the FBI’s own testing, .40 S&W meets their penetration and expansion standards for duty use. It offers more energy than 9mm at the muzzle, and modern hollow points like Federal HST and Speer Gold Dot perform exceptionally well. Per Glock specs, the G23 V MOS is rated for +P ammunition.

Can I use 9mm magazines with this pistol?

No. The G23 V MOS is chambered in .40 S&W and uses specific .40-caliber magazines. Do not attempt to use 9mm magazines — they will not feed correctly and could cause malfunctions. Stick with Glock factory 13-round .40 S&W magazines.
