Description
If you’re looking for a Glock 43X that stands out from the rack, the 9mm 10rd MOS FS Galactic June Bug is the real deal. It’s a factory MOS slide with a Shark Coast Tactical Cerakote finish and a Zaffiri Precision gold barrel, ready to run right out of the box. This is the same slim, 10-round 43X platform trusted for daily concealment, but with custom-level looks and optic-readiness built in.

Key Features
- Galactic June Bug Cerakote finish — WHY IT MATTERS: This isn’t a rattle-can job; it’s a durable, corrosion-resistant coating applied by Shark Coast Tactical that holds up to holster wear and sweat while giving you a one-of-a-kind look.
- Zaffiri Precision gold barrel — WHY IT MATTERS: A match-grade, fluted barrel that improves accuracy and reduces felt recoil, plus the gold finish adds a touch of class without sacrificing reliability.
- MOS (Modular Optic System) slide — WHY IT MATTERS: You can mount your favorite red dot (Shield RMSc, Holosun K series, etc.) directly without sending the slide out for milling. Cuts setup time and keeps your zero consistent.
- Compact grip, subcompact slide — WHY IT MATTERS: The 43X grip fits your hand like a full-size gun for better control, but the slim 1.1-inch slide conceals easily under a T-shirt or jacket.
- Two 10-round magazines included — WHY IT MATTERS: You get a flush-fit mag for deep concealment and a spare for the range or reloads, both with the Glock factory reliability you can count on.
Who It’s For
This Glock 43X is built for the everyday carrier who wants a lightweight, optic-ready 9mm that doesn’t print but still shoots flat. It’s also for the shooter who appreciates custom aesthetics — the Galactic June Bug finish and gold barrel turn heads at the range without compromising function. If you’re a lefty, the ambidextrous slide stop makes it easy to run.

FAQ
Is the Glock 43X MOS FS compatible with all red dot sights?
It uses the Glock MOS footprint, which fits Shield RMSc, Holosun 407K/507K, and similar slim-profile optics. You’ll need a mounting plate for some models, but the MOS system includes the plates you need.
Will the gold barrel affect reliability or accuracy?
No. The Zaffiri Precision barrel is made from 416 stainless steel and is drop-in ready. It’s been test-fired for headspace and timing. The gold is a PVD coating that’s actually harder than the underlying steel, so it resists wear and fouling.
Can I use standard Glock 43X holsters with this Cerakote finish?
Yes, any holster molded for a Glock 43X MOS will work. The Cerakote is about 0.001 inches thick and won’t change fitment. Just avoid kydex holsters with sharp edges that might scratch the finish over time.
Does this model come with the Glock factory warranty?
Yes. Glock covers the frame and slide against defects for one year from date of purchase. Shark Coast Tactical’s Cerakote work is covered by their own warranty — contact them directly for finish issues.
