Tyrant CNC Magazine Extension Features The Tyrant CNC Magazine Extension uses the company s NoBak retention plunger technology allowing the extension to slide onto the bottom of a Sig Sauer P320 magazine in ten seconds or less with no tools required. Removal is just as simple requiring only a push of the plunger before sliding the base pad free. The extension is CNC machined from aerospace grade aluminum and adds up to 5 rounds of 9mm capacity to compatible 15 and 17 round P320 magazines. An included 10 percent power spring ensures the added capacity feeds reliably under the extra demand placed on the magazine. Finished in gold with an added knurl texture the extension is easy to grip and pull free during a fast reload giving competition and defensive shooters a meaningful speed advantage. The base pad is designed to work on both compact and full size P320 frames when paired with their respective magazines though it does require modification to fit certain aftermarket frames like Wilson Combat Agency Arms or iCarus. The added weight from the aluminum base pad also helps the magazine drop free quickly during a reload. For Sig Sauer P320 owners looking to boost capacity and improve reload speed the Tyrant CNC Magazine Extension is available for sale at GrabAGun.
