Tyrant CNC Magazine Extension Features The Tyrant CNC Magazine Extension is built around NoBak Spring Plunger Technology a design that secures the extension firmly to the magazine while still allowing it to be removed and reinstalled without damaging the attachment mechanism. This reliability matters most when shooters are swapping extensions between magazines or performing routine maintenance. The extension adds five rounds of 9mm or .40 S&W capacity specifically to full size M&P 1.0 and 2.0 frame pistols giving a meaningful boost without changing the magazine s overall footprint dramatically. A 10% power spring is included to keep feeding reliable with the added capacity. Serrated sides along the extension give shooters a secure tactile grip during magazine changes a detail that matters most under time pressure at a match or in a defensive scenario. Machined from 6061 aerospace grade aluminum the extension is built to handle repeated drops and reloads without deforming or wearing out. Every dimension is designed specifically around the M&P full size frame so the fit and function align closely with the pistol s factory geometry. For M&P shooters who want more capacity without switching to an entirely different magazine the Tyrant CNC Magazine Extension in Gold delivers a durable purpose built upgrade.
