612789319626 MAGAZINE EXTENSION FOR SIG SAUER P320 Utilizing the Tyrant CNC “NoBak” magazine extension technology, these Sig Sauer P320 magazine extensions are the fastest and easiest installing mag extension on the market.

The extensions are made to fit both compact and full size frames when installed on their respective 15 and 17 round SIG P320 magazines. 10% power spring included with purchase. Why do they install so quickly? Tyrant CNC uses the “NoBak” retention plunger technology that allows the magazine extension to easily slide onto the bottom of your magazine! The entire install happens in 10 seconds or less and with no tools. Want to take it off? Easy, just push the plunger down and slide the magazine base plate off! The SIG SAUER P320 magazine base pads are CNC machined from aerospace grade aluminum. This gives any operator the added weight needed for your base pad to drop free and fast.
