Glock 43x Mos 9mm 3.41 " 10 Round Black Rail Red Dot Ready Pistol

The Glock 43X MOS delivers optic-ready concealed carry in the proven Slimline design. Chambered in 9x19mm, the G43X MOS features slide cuts designed for specific micro-optics and the Glock Slim Mounting Rail for accessory attachment. The 3.41-inch subcompact barrel combined with a comfortably balanced, versatile compact-size grip provides minimal profile for comfortable concealability while maintaining shootability. The MOS system enables direct mounting of popular micro red dot sights for faster target acquisition. Note: Adapter plates are not included.

The G43X MOS incorporates Slimline series features including short trigger distance, frame with built-in beavertail, and reversible magazine catch. The incredibly accurate match-grade Glock Marksman Barrel (GMB) from the Gen5 series delivers enhanced precision, while the tough nDLC finish on the slide provides exceptional wear and corrosion resistance. Precision-milled front serrations aid in press checks and slide manipulation. Ships with one 10-round magazine featuring orange follower for enhanced visibility.

Modular Optic System (MOS)

The MOS slide features precision-milled cuts designed for direct mounting of specific micro-optic footprints. This system eliminates the need for adapter plates with compatible optics, providing lower mounting height and improved co-witness with iron sights. The MOS cuts accept popular micro red dots for fast, both-eyes-open shooting. Note: Adapter plates are not included—verify optic compatibility before purchase.

Slimline Design for Concealed Carry

The G43X MOS combines a subcompact 3.41-inch barrel with compact-size grip length for optimal concealability and control. The slim profile reduces printing under clothing while the compact grip provides sufficient purchase for positive control and recoil management. The frame width mirrors other Slimline models, offering comfortable all-day carry without sacrificing shootability.

Glock Marksman Barrel (GMB)

The match-grade Glock Marksman Barrel features enhanced rifling and improved barrel crown geometry for increased accuracy over standard Glock barrels. The GMB delivers tighter groups and improved precision without sacrificing the legendary Glock reliability and durability.

nDLC Slide Finish

The slide features tough nDLC (Diamond-Like Carbon) finish providing exceptional hardness, wear resistance, and corrosion protection. This advanced coating maintains its protective properties through tens of thousands of rounds and harsh environmental exposure while reducing friction for smooth cycling.

Slimline Series Features

The built-in beavertail provides a higher grip position and protects the shooter's hand from slide bite. The short trigger distance accommodates smaller hands and reduces finger reach. The reversible magazine catch enables left-handed operation or prevents inadvertent magazine release during concealed carry. Precision-milled front serrations provide positive purchase for press checks and one-handed slide manipulation.

Glock Slim Mounting Rail

The integrated accessory rail enables attachment of compact weapon lights and lasers. The slim rail profile maintains the pistol's low-profile dimensions while providing mounting capability for defensive illumination tools.

10-Round Magazine

The slim single-stack magazine holds 10 rounds of 9mm ammunition while maintaining the pistol's concealable profile. The orange follower provides high visibility for quick confirmation of empty magazines. Built to reliable Glock standards, the magazine feeds consistently through thousands of rounds.

The Glock 43X MOS combines optic-ready capability with proven Slimline concealed carry performance—comfortable concealability meets red dot precision.
