Tyrant CNC Glock Magazine Extension Features The Tyrant CNC Magazine Extension is machined from aerospace grade aluminum and measures 1.15 inches in added length giving the shooter four more rounds of 9mm without a bulky conversion. A new uprated power spring ships with the extension to ensure the added capacity still feeds reliably through the full magazine. Smooth chamfered edges on the extension eliminate sharp corners that could snag on clothing or a holster during reholstering. This no tools required design lets an owner swap extensions in the field or at home in minutes. Beyond the added capacity the extension provides a larger gripping surface at the base of the magazine improving purchase and control during reloads under stress. The Gray finish offers a subtle contrast against a black Glock frame while keeping the aluminum construction lightweight. Because installation requires no gunsmithing or special tools shooters can outfit every spare magazine in their rotation the same afternoon. Concealed carry and competition shooters running a Glock 43X or 48 will appreciate the added rounds and improved control this extension delivers.
