About this product
The GLOCK 43X MOS 9MM LUGER 3.41” BBL (2)10RD MAGS COPPER PATINA is a compact MOS-ready striker-fired pistol engineered for concealed carry with optic compatibility. This Ironclad Armory exclusive features a factory-installed Modular Optic System slide cut and distinctive Copper Patina finish over the standard Glock 43X platform, weighing 18.7 ounces unloaded with a 3.41-inch barrel length. The package includes two 10-round magazines, positioning it between subcompact depth and full-size shootability.
What is the GLOCK 43X MOS used for?
This pistol is optimized for daily concealed carry with red dot capability. The MOS system accepts micro red dots like the Holosun 507K without aftermarket machining, while the 3.41-inch barrel provides adequate sight radius for defensive accuracy. At 6.5 inches in overall height with magazine inserted, it maintains concealable dimensions while offering superior grip purchase compared to smaller subcompacts.
How does the GLOCK 43X MOS compare to the SIG Sauer P365 XL?
The 43X MOS prioritizes aftermarket support and holster compatibility over modularity. Where the P365 XL offers serialized fire control unit swapping, the Glock maintains its proven single-piece frame design with superior holster availability and lower bore axis. For shooters prioritizing accessory ecosystem over modular chassis systems, the 43X platform delivers immediate deployment readiness.
What does it weigh and what are the dimensions?
Empty weight measures 18.7 ounces with slide width of 1.1 inches. Overall length is 6.5 inches with a height of 5 inches to the sights, utilizing a 3.41-inch cold hammer-forged barrel. The grip circumference measures 5.8 inches, accommodating medium hands while maintaining concealment under light cover garments.
Who is this NOT for?
This configuration isn't suitable for duty use requiring high-capacity magazines or competition shooters needing optic-ready slides with suppressor-height sights. The MOS system requires separate sight purchase for co-witnessing, and the 10-round capacity limits tactical reload advantages. For high-volume shooters, consider the Stevens 334 Rifle in .308 Winchester.
What's in the box?
Includes two 10-round magazines, MOS cover plates, cable lock, and owner's manual. The Copper Patina finish is applied at the factory level, not an aftermarket coating, ensuring consistent wear characteristics. Magazine followers feature orange followers for immediate round-count visibility during low-light conditions.
Is the GLOCK 43X MOS worth it at $608.99?
At $608.99, this represents a $120 premium over standard 43X models justified by the MOS system and exclusive finish. The MOS cut alone costs $150-200 aftermarket with turnaround times up to 3 weeks, making this factory-ready solution cost-effective for optics adopters. For traditional iron-sight purists, the standard 43X or Stevens 555 Sporting shotgun may better suit budget constraints.

Frequently asked questions
- Is it compatible with Holosun 507K optics?
- Yes, the MOS system accepts Holosun 507K and similar micro red dots using included adapter plates. The RMSc footprint requires Plate #2 from the Glock MOS kit, which ships standard with the pistol. Installation torque spec is 12-15 inch-pounds for optic mounting screws.
- Does it fit standard Glock 43 holsters?
- It fits most Glock 43/43X holsters unless they specifically block MOS slide cuts. The 43X MOS adds 0.1 inch of slide width at the optic cut, which may interfere with tight-fitting leather holsters. Kydex holsters from Vedder or Tulster typically accommodate the MOS profile without modification.
- How long does shipping take?
- Ironclad Armory processes orders within 2 business days with 3-5 day transit via FedEx. All firearms ship to your selected FFL dealer, who will conduct the required background check per ATF regulations. California residents add 2 additional days for CFLC clearance.
- Can I return it if it doesn't fit my hand?
- Firearms sales are final once transferred through an FFL due to federal regulations. We recommend handling a standard Glock 43X at your local dealer to confirm grip dimensions before purchasing. The 43X grip circumference measures 5.8 inches compared to 5.2 inches on the standard Glock 43.
- Does this work with Glock 48 magazines?
- Yes, the 43X accepts Glock 48 10-round magazines interchangeably. Both models share the same magazine catch geometry and feed ramp configuration. Aftermarket 15-round magazines from Shield Arms require their metal magazine catch for reliable function.
