• Integrated Slimline Rail: Allows for direct attachment of weapon-mounted lights and lasers designed for the GL450 rail (e.g., SIG SAUER TLR-6, SureFire XSC).
• Grey Frame Color: Aesthetic factory color offering a distinct, modern look compared to standard black.
• Slim, Ergonomic Grip: Significantly thinner profile than standard double-stack Glocks for superior concealability and comfort.
• Rough Textured Grip: Enhanced grip texture on the sides and front strap for secure handling in all conditions.
• Modular Backstrap: Allows for minor customization of grip circumference to fit various hand sizes (not all models).
• Beavertail Design: Helps position the hand high on the grip, mitigating recoil and preventing “Glock bite.”
• Factory Glock Components: Designed to house all factory Glock 43X internal components (trigger mechanism, slide lock, etc.).

• Enhanced Capability: The rail transforms the G43X from a pure-concealment piece to a more versatile option capable of hosting a WML (Weapon-Mounted Light) for low-light identification and target acquisition.
• Improved Concealment & Comfort: The slim frame is easier to conceal and more comfortable to carry for extended periods, especially for individuals with smaller hands.
• Superior Control: The aggressive texturing and beavertail design provide a secure, controllable grip for faster follow-up shots and overall better handling.
• Customization & Aesthetics: The unique grey color offers a personalized look for builders and enthusiasts looking to create a custom pistol.
• Reliability: Maintains the legendary Glock reliability and simplicity in a compact, railed frame platform.

• Legal Note: In the United States, the frame is the federally regulated serialized part (the “firearm”). Purchasing this frame requires a background check through an FFL (Federal Firearms Licensee).
• Build Project: This frame is ideal for a “Build-Your-Own” project. You will need to source a complete G43X slide assembly, barrel, recoil spring assembly, and all lower parts kit components to build a functional firearm.
• Rail Compatibility is Key: Ensure any light or laser you purchase is explicitly compatible with the “Glock Slimline Rail” or “GL450” rail. Standard Picatinny accessories will not fit without an adapter.
• Magazine Compatibility: The G43X frame is designed to use Glock 43X magazines (10-round OEM) and aftermarket options like the Shield Arms S15 magazines (15-round), which may require a metal magazine catch.
• Not a Standalone Product: This is a component, not a complete firearm. It requires additional parts and professional gunsmithing knowledge for proper assembly to ensure safety and reliability.
