Tyrant CNC Glock 42 Plus 2 Magazine Extension - Fits OEM Glock 42 .380 ACP Magazines, Plus 2 Round Capacity Boost, Rapid Detach Toolless Retention, 6061-T6 Aluminum, Anodized Black Finish - TD-G42MAGEX-BLK / 612789319145
Product Description
Upgrading a deep-concealment backup pistol, sub-compact defensive platform, or everyday carry (EDC) magazine staging array requires extension modules built to absolute locking and parsing tolerances. Low-grade polymer extensions often lack internal rigidity, flexing under full spring pressure and leading to follower binding or failure-to-feed hang-ups on your bench. The **Tyrant CNC® Glock 42 +2 Magazine Extension (TD-G42MAGEX-BLK / 612789319145)** completely flatlines these capacity limitations and structural vulnerabilities. It delivers a premium **plus-two capacity boost** matched with a toolless rapid-detach anchor layout.
Proudly engineered, CNC-machined, and performance-verified in the United States by Tyrant CNC, this high-strength ergonomic enhancement is carved from a solid block of high-tensile **6061-T6 structural aircraft-grade aluminum alloy** finished in a deep, non-reflective matte black anodized dressing. The core engineering choice features a proprietary **spring-loaded retention plunger pin design**, allowing armorers to slide the extension onto the factory magazine tabs and lock it instantly without clumsy set screws or loose retaining plates. Adding an extra 2 rounds of .380 ACP ammunition to your payload, the extended profile creates a perfect lower grip ledge, giving your pinky finger a firm anchor point to control muzzle flip during rapid fire straight from your workbench.
Engineered to slide cleanly onto standard factory OEM Glock 42 single-stack magazines, this factory-calibrated metal extension ensures absolute mechanical synchronization directly from your workspace bench.
*Armorer Bench Notes & Real-World Magazine Staging Guidance: The Tyrant CNC TD-G42MAGEX-BLK enhancement block arrives workspace ready, containing the anodized aluminum extension base, a custom-wound high-tensile heat-treated steel magazine spring, and the pre-installed plunger retention lock. PROPRIETARY GLOCK 42 OEM INTERFACE MATRIX: The upper mounting tracks are engineered natively, strictly, and dimensionally to slide onto **factory original Glock OEM 42 .380 ACP single-stack magazine bodies**. *Aftermarket Magazine Compatibility Checklist:* Verify on your armorer bench that you are utilizing original polymer-jacketed Glock steel tubes—this precise tracking channel is **NOT guaranteed to interface properly with aftermarket clear polymer or pure steel sheet magazine body shell variants**. Armorer Workbench Custom Staging Sequence: 1. Visually and physically confirm your host Glock 42 pistol is completely clear of live ammunition, the magazine is removed, and the frame chamber area is verified empty and safe. 2. Secure a punch tool to press the factory magazine inner base insert pin downward through the access hole in the bottom of the stock plastic floorplate. 3. Carefully slide the stock baseplate forward off the tracking tabs, keeping your thumb firmly over the bottom opening to trap the compressed factory spring inside the tube cavity. 4. Extract the original spring and plastic floorplate insert, clean the inner magazine walls with a dry cleaning brush, and slide in the new custom-wound extended spring provided in the Tyrant kit. 5. Compress the extended spring upward inside the tube, hold it flush with the base rim, and depress the cross-plunger pin on the back side of the Tyrant aluminum extension. 6. Slide the aluminum extension onto the magazine body rails from front to back until it clicks loudly into battery, then pull down firmly to verify the retention plunger pin has locked completely home into the rear indexing slot before loading downrange.*
