The Glock G43X Sub-Compact Frame 9mm Luger 10+1 3.41" Black GMB Barrel, Black nDLC Serrated Steel Slide, Mahi Polymer Frame w/Front Rail & Beavertail, Black Textured Grip, Ambidextrous UX4350204MAHIFR (UPC 810100237387) is a slim, lightweight concealed-carry pistol that combines classic Glock reliability with a bold Mahi frame finish and a rugged black slide. Built on Glock’s popular Slimline 43X platform, this model offers 10+1 rounds of 9mm in a highly concealable package with a full, controllable grip and accessory-ready front rail.
Compact 9mm Power for Everyday Carry
The G43X is designed specifically for everyday concealed carry. It uses Glock’s Slim Sub-Compact frame size, giving you a thin profile that hides easily but still offers a full grip length for better control.
Caliber: 9mm Luger
Capacity: 10+1 rounds with factory OEM magazines
Barrel Length: 3.41" Glock Marksman Barrel (GMB) for enhanced accuracy and consistency
Frame Size: Slim Sub-Compact – optimized for concealed carry and reduced printing under clothing
Compared to micro-compact single-stack pistols, the G43X gives you more on-board ammunition and a more stable grip, without stepping up to the bulk of a double-stack duty gun.
Black nDLC Serrated Steel Slide – Durable & Low-Glare
This G43X configuration features a black nDLC (Diamond-Like Carbon) coated steel slide. The nDLC finish is designed for serious use, offering:
Excellent resistance to corrosion and surface wear
A low-glare, non-reflective appearance for defensive and tactical use
Enhanced hardness to withstand holster wear and daily carry
Front and rear slide serrations provide a secure grip for press checks and manipulations, even with wet or gloved hands.
Inside the slide is the 3.41" Black GMB barrel, using Glock’s updated rifling and crown geometry to tighten groups at typical defensive distances while maintaining Glock’s reputation for durability and reliability.
Mahi Polymer Frame with Front Rail & Beavertail
The standout feature of this model is its Mahi polymer frame, finished in a vibrant Mahi Cerakote tone that evokes coastal-gamefish colors while giving the pistol a unique, custom-shop look straight from the factory.
Functionally, the frame is loaded with carry-focused features:
Integrated beavertail to encourage a high, secure grip and help prevent slide bite
Front accessory rail for mounting compact weapon lights or lasers, making the pistol low-light ready out of the box
Slim contour to aid concealment, especially in IWB and appendix carry positions
The Cerakote finish on the frame is not just cosmetic—it provides additional resistance to sweat, oils, and everyday handling, ideal for a pistol that will be carried daily.
Black Textured Grip – Secure Control in a Slim Package
The black textured grip panels contrast sharply with the Mahi frame and are engineered for a secure hold without being overly abrasive against skin or clothing.
Combined with the beavertail and Glock’s familiar grip angle, this configuration offers:
Confident control during rapid strings of fire
Better recoil management compared to ultra-small micro 9mms
A comfortable shooting experience for extended training sessions
This balance of slim dimensions and full grip makes the G43X easier to shoot well, especially for newer shooters or those with larger hands.
Safe Action System & Proven Glock Reliability
The Glock G43X uses Glock’s well-known Safe Action® System, which incorporates three internal, automatically operating safeties that disengage only when the trigger is pulled and re-engage when it’s released.
Key reliability and safety features include:
DAO-style striker-fired action with a consistent trigger pull from the first shot to the last
Firing pin safety, drop safety, and trigger safety working together for built-in security
Hardened steel slide rails integrated into the polymer frame
Simple field-stripping and maintenance with wide parts and holster support across the industry
Glock’s track record in duty, competition, and concealed carry roles means this G43X Mahi variant brings the same core reliability, with a more distinctive look and enhanced carry features.
Slimline Dimensions for All-Day Carry
Despite its full firing grip and 10-round magazine, the 43X remains extremely manageable for daily carry:
These dimensions give you:
A longer sight radius than many ultra-compact 9mms
Enough slide mass and grip area for comfortable shooting
A profile that remains easy to conceal under a light cover garment
