GLOCK 43X MOS 9mm Sub-Compact Striker-Fired Pistol
The GLOCK 43X MOS is a slim, optics-ready 9mm built for concealed carry and personal defense. It combines GLOCK's proven striker-fired action with a 3.41-inch Marksman Barrel, nDLC finish, and the MOS optics mounting system for modern sight options. This is a complete, ready-to-carry pistol that ships with two 15-round magazines.

Optics-Ready Design and Modularity
The MOS system lets you mount popular red dot and reflex sights without gunsmithing or permanent alterations. The mounting system accepts multiple footprints, so you can choose optics based on your preference and budget. The fixed sights remain functional if you run the pistol without an optic, or they coexist beneath mounted glass. This flexibility means your pistol adapts to your setup, not the other way around.
Slim Profile for Everyday Carry
The 43X platform uses a narrower slide and frame compared to full-size GLOCK models, making it genuinely easier to carry all day without printing. The no-finger-groove design accommodates different hand sizes, and the 3.41-inch barrel keeps overall length compact while maintaining sight radius for accuracy. Weight is kept minimal, reducing fatigue during extended wear.
Marksman Barrel and Accuracy
GLOCK's Marksman Barrel improves shot placement through tighter tolerances and enhanced rifling. The 3.41-inch length balances velocity, control, and concealability. Recoil impulse remains manageable, and follow-up shots track faster than shorter-barreled pistols. This matters for both defensive accuracy and range training.
nDLC Finish and Durability
The nDLC (nitrided diamond-like carbon) coating is harder than standard Tenifer and resists scratches, corrosion, and wear from daily carry. It maintains function in wet environments and reduces maintenance compared to uncoated steel slides. The finish is thin enough that it doesn't affect fit or function.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Optics mounting requires verification of footprint compatibility before installation.
