Key Features
- MOS Optics Cut — Why it matters: You can mount a red-dot without sending the slide to a machine shop. The cut accepts the most common micro dots, so you get faster target acquisition in low-light or high-stress situations.
- Custom Lady Bug Cerakote — Why it matters: This isn’t a factory finish you’ll see on every other 43X. Shark Coast Tactical applies a durable, corrosion-resistant coating that stands out in a holster and holds up to daily carry sweat.
- Zaffiri Precision Gold Barrel — Why it matters: Match-grade accuracy with a corrosion-resistant gold PVD coating. The barrel improves consistency shot to shot, and the gold finish adds a touch of class to your EDC.
- Slim, Compact Grip — Why it matters: The 43X grip is longer than a standard 43 but still slim enough for AIWB carry. You get a full three-finger purchase without printing under a T-shirt.
- Fixed Backup Sights — Why it matters: Even if your red-dot battery dies, you have iron sights that co-witness through the optic window. No need to swap out plates or lose zero.
Who It’s For
This pistol is built for the urban CCW holder who wants a compact 9mm with optics capability and a custom look. Apartment dwellers who need a reliable home-defense tool that doubles as a daily carry piece will appreciate the 10-round capacity and slim profile. It also fits shooters who prefer a smaller frame than a Glock 19 but still want a grip long enough to control recoil.
Pros & Cons
- Pro: MOS cut gives you red-dot flexibility without aftermarket milling.
- Pro: Custom Cerakote and gold barrel make it visually distinct from stock Glocks.
- Pro: Slim grip width (1.1 inches) improves concealment and comfort for all-day carry.
- Con: The 10-round magazine is the max standard capacity for the 43X frame. If you need more than 10 rounds, you’ll need to look at aftermarket extended mags or switch to a Glock 19.

FAQ
What is Glock 43X MOS?
The Glock 43X MOS is a compact, striker-fired 9mm pistol with a Modular Optics System (MOS) cut on the slide, allowing direct mounting of micro red-dot sights without adapter plates. It has a slim subcompact slide but a longer grip than the standard G43, giving you a full firing grip and 10-round capacity.
What magazines are compatible with Glock 43X?
The Glock 43X MOS uses Glock 43X magazines (10-round flush-fit). It also accepts Shield Arms S15 magazines (15-round capacity) and PSA Micro Dagger magazines (15-round), but those are aftermarket. Factory 43 or 48 magazines will NOT fit due to different frame widths.
Is the Glock 43X MOS compatible with the Holosun 407K?
Yes. The MOS cut on the 43X accepts Holosun 407K, 507K, and EPS Carry models directly, though you may need to file down the rear locating lugs on the slide or use a thin adapter plate for a perfect fit. Many shooters run a 507K with no issues.
What is the difference between Glock 43X and 43X MOS?
The standard Glock 43X has a solid slide with fixed sights only. The 43X MOS has an optics cut (MOS) and comes with a set of suppressor-height sights that co-witness with a red-dot. The MOS model also has a slightly different slide profile to accommodate the cut.
