Glock 43X MOS: A Top-Tier Choice for Concealed Carry
When it comes to concealed carry, the Glock 43X MOS stands out as one of the best options on the market. Combining Glock’s legendary reliability with modern upgrades tailored for everyday carry, the 43X MOS delivers a balance of capacity, comfort, and customization that makes it a standout choice for self-defense.
Compact Yet Capable
The Glock 43X MOS builds on the success of the original 43X by maintaining its compact size while adding a Modular Optic System (MOS) for enhanced versatility. With an overall length of 6.5 inches, a height of 5.04 inches, and a slim 1.1-inch width, this pistol is perfect for inside-the-waistband (IWB) carry, minimizing printing while remaining comfortable for all-day wear.
Despite its compact size, the 43X MOS boasts a 10+1 round capacity, offering more firepower than traditional single-stack micro-compacts while maintaining a slim profile. Additionally, aftermarket magazines, such as the Shield Arms S15, can boost the capacity to 15 rounds, making this pistol even more formidable.
Enhanced Concealability and Ergonomics
One of the biggest advantages of the 43X MOS is its ergonomic grip. The slimline frame provides a comfortable, secure hold that accommodates shooters of all hand sizes, while the textured surface enhances control during rapid fire. Unlike many micro-compacts that feel too small for a full grip, the 43X MOS allows for a natural hold without sacrificing concealability.
At just 18.7 ounces unloaded, the lightweight design ensures that carrying all day doesn’t lead to fatigue. Paired with a quality holster, such as those from Tier 1 Concealed or Vedder Holsters, the 43X MOS disappears under clothing, making it an excellent choice for appendix or strong-side carry.
Optics-Ready for Maximum Versatility
The MOS cut on the 43X allows users to easily mount a red dot optic, such as the Holosun 507K or Trijicon RMRcc, enhancing accuracy and target acquisition. Red dot sights have become increasingly popular for defensive handguns, offering faster sight alignment, improved accuracy under stress, and better performance in low-light situations.
The factory front and rear slide serrations provide excellent grip for slide manipulation, and the Glock Marksman Barrel (GMB) ensures improved accuracy compared to previous generations.
Glock Reliability and Simplicity
Glock’s reputation for reliability is one of the biggest selling points of the 43X MOS. Whether you’re using factory magazines or aftermarket options, this pistol runs consistently with a wide range of ammunition types. Glock’s Safe Action System provides a consistent 5.4 lb trigger pull, passive safety features, and a smooth reset for fast follow-up shots.
Additionally, Glock’s simple design means easy maintenance. Field stripping and cleaning require no tools, and the widespread availability of parts ensures that customization and repairs are straightforward.
