Glock 43X MOS 9mm Luger Optic-Ready 2x10rd Black
The Glock 43X MOS 9mm Luger Optic-Ready 2x10rd Black is a subcompact everyday carry pistol built around the MOS (Modular Optic System) platform. It combines a slim, concealable slide with a compact grip, a black polymer frame with a short accessory rail, and factory fixed sights — ready to mount a miniature red-dot optic (adapter plates sold separately). Two 10-round magazines and standard Glock safeties round out the package.

Key Features
- MOS Optic-Ready Slide — Why it matters: You can mount a miniature red-dot directly onto the slide without sending it to a gunsmith. Adapter plates (sold separately) let you use brands like Holosun, Shield, or Trijicon for faster target acquisition.
- Slim, Concealable Profile — Why it matters: At just under 1 inch wide, this pistol hides under a T-shirt or light jacket without printing. It’s built for all-day comfort, not range-bag storage.
- Compact Grip with 10-Round Capacity — Why it matters: The grip is long enough for a full firing grip but short enough to tuck. Two 10-round magazines give you 10+1 on tap, which is solid for a subcompact 9mm.
- Short Accessory Rail — Why it matters: You can attach a compact light or laser for low-light identification. That’s a big deal for an EDC gun that might see duty after sunset.
- Factory Fixed Sights — Why it matters: Even if you run an optic, the irons are there as a backup. No need to upgrade right out of the box — shoot it as-is, then decide.
Who It’s For
This Glock 43X MOS is for the daily carrier who wants to run an optic without the bulk of a full-size gun. It’s for the guy or gal who carries appendix, strong-side, or in a belly band and needs a reliable 9mm that disappears under clothes. If you’re building a lightweight EDC kit and don’t want to mess with aftermarket slide milling, this is your starting point.
Pros vs. Cons
- Pro: Factory optic cut means no wait time or extra cost for slide work. Con: Adapter plates are sold separately — budget $20–40 extra if you plan to mount a red-dot.
- Pro: Glock reliability and aftermarket support. Parts, holsters, and mags are everywhere. Con: Trigger is the standard Glock 5.5 lb pull — not as crisp as an aftermarket trigger, but consistent.
- Pro: Slim profile makes it one of the most concealable 9mm pistols on the market. Con: The 10-round mag limit means you’ll reload sooner than with a 15-round compact.
Comparison
| Feature | Glock 43X MOS | Zev Technologies OZ9C | Agency Arms Syndicate |
|---|---|---|---|
| Optic-Ready | MOS (RMSc footprint) | RMSc + RMR cuts | RMR cut (direct mount) |
| Capacity | 10+1 | 15+1 (Glock 19 mags) | 15+1 (Glock 19 mags) |
| Weight (unloaded) | 18.5 oz | 24.5 oz | 22 oz |

| Best For | Budget-friendly EDC with optic option | Competition-ready build | Custom duty gun |
According to Glock specs, the 43X MOS weighs just 18.5 oz unloaded — that’s lighter than both the Zev OZ9C and the Agency Syndicate, making it a top pick for all-day carry without the premium price tag. One honest drawback: the factory trigger pull is heavier than aftermarket options, so if you’re used to a 3.5 lb trigger, plan on a swap.
FAQ
Does the Glock 43X MOS come with optic plates?
No, the pistol ships with two 10-round magazines and a cleaning kit. Adapter plates for specific optics (like Holosun 407K/507K, Shield RMS, or Trijicon RMRcc) are sold separately. You’ll need to buy the correct plate for your chosen optic.
What optics fit the Glock 43X MOS without an adapter plate?
The MOS cut uses the Shield RMSc footprint. Optics like the Holosun 407K/507K, Shield RMS, and Sig Sauer Romeo Zero can mount directly with the right screws. For other footprints (RMR, Docter, etc.), you’ll need the Glock MOS adapter plate kit.
Is the Glock 43X MOS the same size as the standard 43X?
Yes, the dimensions are identical — 6.5 inches overall length, 4.25 inch height, and 1.06 inch width. The only difference is the MOS slide cut and the short accessory rail on the frame. It fits most 43X holsters, but check for optic clearance.
Can I use Glock 43 magazines in the 43X MOS?
No, the 43X MOS uses a longer grip that accepts 10-round magazines specifically designed for the 43X/48 platform. Glock 43 magazines are shorter and won’t lock in. Stick with factory 43X mags or aftermarket options from Shield Arms or PSA.
How reliable is the Glock 43X MOS with optics?
Very. The MOS system has been proven across thousands of units. Per Glock specs, the slide is machined to maintain recoil spring geometry and ejection reliability. As long as you torque the optic screws to spec (15 in-lbs), it runs as reliably as a standard 43X.
Ready to Carry?
The Glock 43X MOS 9mm Luger Optic-Ready 2x10rd Black is a solid choice for anyone building a lightweight, optics-ready EDC setup. With a slim profile, factory reliability, and a price that won’t break the bank, it’s one of the most practical subcompact 9mm pistols on the market. According to industry stats, Glock holds over 65% of the law enforcement handgun market — this model brings that same dependability to your daily carry.
