The Tyrant CNC +4 Magazine Extension For Glock 43X/48 Black is engineered to boost the capacity and handling of Glock’s slimline crossover pistols. CNC machined from aerospace-grade aluminum, this extension replaces the factory base plate on OEM 10-round magazines and immediately adds four rounds of 9mm. The added weight helps magazines drop free more consistently, while the sculpted exterior and knurled surfaces provide a secure purchase during reloads.

Designed specifically for Glock 43X and Glock 48 magazines, this extension installs in seconds using Tyrant’s retention plunger system, with no tools required. A 10% power spring is included to support the increased capacity and reliable feeding. Whether you are refining your everyday carry setup, spending time at the range, or training for competition, this compact extension offers extra rounds and improved control in a streamlined package that reflects Tyrant’s focus on thoughtful design and precise machining.
