Tyrant Cnc Tdp320Magexgold Mag Ext Sig P320 5Rd Gold Alumn

The Tyrant CNC TDP320MagEx Gold is a 5-round magazine extension built for the SIG Sauer P320, engineered to give you faster reloads and a more confident grip when it matters. If you shoot a P320 in competition, training, or defensive use, this aluminum base pad pad extends your 15 or 17-round factory magazine by five rounds, giving you more rounds downrange without swapping mags as often. The standout feature is Tyrant's proprietary NoBak retention system—a tool-free installation that takes roughly 10 seconds and zero fiddling.

Built from 6000-series aluminum and CNC machined to tight tolerances, the extension features added weight to help your magazines drop free and fast, plus a knurled grip surface that works in wet, cold, or sweaty conditions. The gold anodize isn't just for looks; it's a durable finish that stands up to regular use. Installation is genuinely quick: the plunger-based system lets you slide the extension onto your magazine without tools, and removal is just as easy—push the plunger and slide it off. Every extension ships with a new power spring, ready to go out of the box.

Fitment is broad but specific: the TDP320MagEx works on both 15 and 17-round P320 magazines and fits standard P320 compact and full-size frames. It also works on several aftermarket frames (AXG, Wilson Combat, Icarus, Agency Arms, and X5 Legion) when installed on those respective base magazines, though some may require minor modification depending on magwell design. This extension does not fit the 10, 12, or 21-round P320 magazine variants.

Whether you're logging range time, training for a match, or building out a duty gun, this Tyrant CNC extension delivers real-world ergonomic gains—faster reloads and more ammunition capacity without the bulk of a larger gun.
