About this product

What is the Glock G23 V MOS .40 S&W 4.02in Optic-Ready Compact? It's a striker-fired semi-automatic pistol chambered in .40 S&W with a factory-milled MOS slide that accepts miniature red dot optics using included adapter plates. This compact platform maintains duty-grade reliability while accommodating modern sighting systems, and comes with three 13-round magazines for immediate deployment.

What is the Glock G23 V MOS used for?

This pistol serves as a concealable duty or defensive firearm that bridges traditional iron sight reliability with modern red dot capability. The .40 S&W cartridge delivers 400 foot-pounds of muzzle energy from its 4.02-inch barrel, making it suitable for home defense and law enforcement backup roles where optic-equipped firearms are increasingly standard. Its compact dimensions allow for discreet carry while maintaining sufficient grip surface for controlled shooting.

How does the Glock G23 V MOS compare to the Stevens 334 .308 Win?

The G23 V MOS fills a completely different role than the Stevens 334 .308 Win bolt-action rifle—this is a compact semi-automatic pistol for personal defense versus a precision hunting rifle. Where the Stevens requires manual cycling and excels at 200+ yard engagements, the Glock provides rapid follow-up shots within 25 yards and weighs just 23.5 ounces unloaded compared to the Stevens' 6.8 pounds. The Glock's optics system accommodates miniature red dots while the Stevens uses traditional rifle scopes.

What does it weigh and what are the dimensions?

The pistol weighs 23.5 ounces with an empty magazine and measures 7.36 inches in length with a 4.02-inch cold hammer-forged barrel. Height stands at 5.04 inches including the magazine, and width measures 1.34 inches at the slide—compact enough for concealed carry while providing adequate grip real estate for shooters with medium to large hands. The 13-round magazine capacity balances firepower with concealability.

Who is this NOT for?

This pistol isn't suitable for new shooters uncomfortable with the .40 S&W's snappy recoil impulse or those seeking a minimalist micro-compact for deep concealment. The 23.5-ounce weight and 1.34-inch width make it bulkier than subcompacts like the Glock 43X, and the .40 S&W cartridge demands more practice to master than 9mm alternatives. Shooters who prefer revolvers or those operating in jurisdictions with magazine capacity restrictions should consider other options.

What's in the box?

You receive the pistol itself, three 13-round magazines, MOS adapter plates for various optic footprints (including Trijicon RMR and Holosun 507C), a cable lock, cleaning rod, and magazine loader. The package includes all necessary tools for optics mounting—notably missing are suppressor-height sights, which must be purchased separately if co-witnessing with optics is desired. Total unboxed weight with all components is approximately 3.2 pounds.

Is the Glock G23 V MOS worth it at $648.99?

At $648.99, this represents solid value for shooters specifically needing .40 S&W performance with optics readiness in a compact package. The included MOS system typically adds $150-200 over non-optic models, and three magazines represent a $75 value alone. Compared to aftermarket slide milling services that cost $200+ and void warranties, the factory MOS solution provides guaranteed reliability and maintains Glock's legendary customer support.

Pros & cons

What works

  • Factory MOS slide accepts optics without aftermarket milling—saves $200+ and maintains warranty
  • Includes three 13-round magazines—$75 value compared to typical single-magazine packages
  • nDLC finish provides 60% better corrosion resistance than standard Tennifer treatment
  • 4.02-inch Marksman barrel delivers consistent 3-inch groups at 25 yards with quality ammunition

Trade-offs

  • Requires separate $80-120 purchase of suppressor-height sights for proper optic co-witness
  • .40 S&W recoil impulse is 30% sharper than 9mm—not ideal for new shooters
  • MOS plate system adds 0.2 inches of height over direct-milled optics solutions
  • No front slide serrations—limits press-checking options compared to Gen5 MOS models

Expert review

I tested this G23 V MOS over 600 rounds of Federal HST 180gr and Speer Gold Dot 165gr during a three-day defensive pistol course in Montana's variable spring conditions. The nDLC finish showed zero corrosion despite intermittent rain, and the MOS system maintained zero through all drills—something I've seen fail on aftermarket milled slides in similar conditions. Compared to the Smith & Wesson M&P 2.0 Compact .40, the Glock's trigger breaks cleaner at 5.5 pounds versus the M&P's spongy 6.2-pound pull, though the M&P's aggressive grip texturing provides better control during rapid strings. The Glock's MOS system also offers more optic options than the M&P's specific Shield RMSc footprint. The surprise came during malfunction drills—the MOS plate's added height occasionally snagged on clothing during one-handed manipulations, something that doesn't happen with direct-milled slides. I also found the lack of front serrations frustrating when demonstrating press checks to students, requiring them to use the optic itself for manipulation. Buy this if you need .40 S&W performance with optics readiness and value Glock's legendary reliability above custom features. Skip it if you prefer softer-shooting 9mm or want ultimate concealment—the width and weight make it less comfortable for all-day carry than slimmer options. For the shooter who understands the .40 S&W's trade-offs and wants optics capability without warranty concerns, this executes perfectly.

Frequently asked questions

Is it compatible with Trijicon RMR optics?
Yes, the included MOS plate #2 provides direct mounting for Trijicon RMR and SRO optics without modification. The mounting system uses Torx T10 screws that should be torqued to 15 inch-pounds per Glock's specification to maintain zero under recoil.
Does it fit Glock 19 holsters?
No—the G23's slide width of 1.34 inches and frame dimensions differ slightly from the G19. You'll need holsters specifically designed for Gen 4 or Gen 5 Glock 23/32 models. Custom holster makers like T Rex Arms and Tier 1 Concealed offer optics-ready options for this platform.
How long does shipping take?
Firearms shipping requires 3-5 business days for processing plus transit time to your selected FFL dealer. All shipments require adult signature confirmation and cannot be left unattended—plan to coordinate pickup with your dealer within 30 days of delivery notification.
Can I return it if it doesn't fit my hand?
No—firearms sales are final once transferred through an FFL due to federal regulations. We recommend handling the pistol at a local dealer before purchase. The grip circumference measures 5.8 inches, which suits medium to large hands best.
