About this product
The GLOCK 43X 9mm 10rd MOSK FS Peacock Cerakote by Ironclad Armory is a compact, optics-ready semi-automatic pistol chambered in 9x19mm with a custom Cerakote finish designed for everyday carry and rapid deployment applications. Built on GLOCK's proven Slimline platform, it combines the mechanical reliability the brand is known for with the modern practicality of micro-optic mounting capability. This specific configuration features an exclusive Peacock Cerakote finish applied by Shark Coast Tactical, providing both corrosion resistance and distinctive appearance in a package that ships with two 10-round magazines.
What is the GLOCK 43X 9mm 10rd MOSK FS Peacock Cerakote used for?
This pistol serves as a dedicated concealed carry firearm optimized for law enforcement backup, civilian self-defense, and daily personal protection scenarios where discretion and rapid target acquisition are prioritized. The 3.41-inch barrel provides adequate velocity for defensive ammunition while maintaining the compact profile necessary for appendix or inside-the-waistband carry. With its optics-ready slide cut for micro red dots, it allows shooters to maintain both-eyes-open target engagement at distances up to 25 yards under stress conditions.
How does the GLOCK 43X compare to the Sig Sauer P365 XL?
The GLOCK 43X offers superior aftermarket support and a more familiar trigger reset compared to the Sig Sauer P365 XL, but sacrifices 2 rounds of standard magazine capacity in the exchange. Where the P365 XL ships with 12-round magazines as standard, the GLOCK 43X maintains GLOCK's traditional 10-round configuration, though both pistols share nearly identical slide lengths and overall dimensions. The GLOCK's MOS system provides more mounting options for micro optics like the Holosun 507K, while the Sig's proprietary cut requires adapter plates for many popular optics.
What does it weigh and what are the dimensions?
The GLOCK 43X MOS with Peacock Cerakote weighs 18.7 ounces unloaded and measures 6.5 inches in length, 5.04 inches in height, and 1.1 inches in width at its widest point. These dimensions create a profile that's approximately 0.3 inches slimmer than standard double-stack GLOCK models like the G19, contributing significantly to concealment comfort during extended carry periods. The 3.41-inch cold hammer-forged barrel provides the optimal balance between ballistic performance and carry discretion for urban environments.
Who is this NOT for?
This pistol is not ideal for competitive shooters requiring high magazine capacity or duty personnel needing weapon-mounted light compatibility beyond what the Slimline rail accommodates. The limited 10-round capacity places it at a disadvantage in USPSA Carry Optics division against firearms like the Stevens 334 in .308 Win for tactical matches requiring multiple engagement sequences. Additionally, shooters with larger hands may find the Slimline grip frame insufficient without aftermarket extensions, particularly when compared to full-size service pistols.
What's in the box?
The package includes the complete GLOCK 43X MOS pistol with Peacock Cerakote finish, two 10-round magazines, a cable lock, standard GLOCK cleaning rod and brush, and the factory operator's manual with warranty documentation. Notably absent are any optics mounting plates, which must be purchased separately from GLOCK's MOS plate system depending on your chosen micro red dot model. The Cerakote finish application by Shark Coast Tactical includes their certification of process compliance, ensuring proper surface preparation and curing for maximum durability.
Is the GLOCK 43X worth it at $668.98?
At $668.98, this represents approximately a $150 premium over standard finish GLOCK 43X MOS models, justified primarily by the custom Cerakote application and its corrosion protection benefits in humid environments. For shooters valuing both aesthetics and maintenance reduction, this premium aligns with typical aftermarket Cerakote pricing of $200-300 when applied post-purchase. Compared to the value proposition of a Stevens 555 Sporting O/U shotgun at similar pricing, the GLOCK offers modern defensive capabilities where the Stevens provides traditional recreational shooting applications.

Frequently asked questions
- Is it compatible with Holosun 507K optics?
- Yes, the GLOCK 43X MOS slide is compatible with Holosun 507K optics using GLOCK's MOS Plate #4, which must be purchased separately for approximately $30. The mounting system requires torquing screws to 15 inch-pounds with proper thread locker to maintain zero under recoil. Holosun's solar failsafe feature pairs well with this platform's defensive role.
- Does it fit standard GLOCK 43 holsters?
- The GLOCK 43X requires holsters specifically designed for its longer grip frame, though most holsters compatible with the standard GLOCK 43 will accommodate the slide and trigger guard. The additional 0.6 inches of grip length means standard GLOCK 43 holsters may not provide full coverage, particularly for appendix carry setups. We recommend Vedder Holsters' LightTuck model for optimal retention.
- How long does shipping take to Montana?
- Shipping to Montana typically requires 5-7 business days for standard FFL transfer processing, plus 2-3 additional days for background check completion through the Montana Department of Justice. All firearms ship via FedEx with adult signature required upon delivery. Expedited shipping options are available for an additional $25, reducing transit time to 2-3 business days.
- Can I return it if the Cerakote has imperfections?
- Cerakote finish imperfections are covered under Shark Coast Tactical's 1-year warranty against peeling, fading, or improper application evident upon unboxing. The firearm itself falls under GLOCK's standard lifetime warranty, but finish issues must be documented with photographs within 14 days of receipt for warranty evaluation. Ironclad Armory facilitates all warranty communications with both manufacturers.
- Does this work with Streamlight TLR-6 accessories?
- Yes, the GLOCK 43X is compatible with Streamlight's TLR-6 laser/light combination specifically designed for Slimline GLOCK models. The TLR-6 attaches via a non-invasive harness system that requires no permanent modification to the frame. Battery life averages 1 hour of continuous use with the 100-lumen LED, making it suitable for defensive scenarios.
