Tyrant Cnc Tdp320Magexblack Mag Ext Sig P320 5Rd Black Alumn
$38.83
The Tyrant CNC TDP320MagEx is a 5-round magazine extension designed for the SIG Sauer P320, engineered to add capacity and control without the typical installation hassle. Built from 6061 aerospace-grade aluminum and CNC-machined for precision fit, this mag extension slides onto the bottom of your existing 15 or 17-round P320 magazine in seconds—no tools required. If you shoot a P320 and want faster reloads with better grip, this extension gets out of the way and lets you focus on what matters.
The real standout here is Tyrant CNC's "NoBak" retention-plunger technology. Instead of fiddling with screws or epoxy, you simply align the extension and slide it home. Removal is just as straightforward: press the plunger and slide off the base pad. That simplicity means you can swap setups in seconds if you're testing magazine configurations or switching between range and duty use. A 10% power spring comes in the box to ensure smooth feeding and reliable lock-up with the added extension.
The aluminum construction gives the mag the weight it needs to drop free every time, and the knurled (textured) grip surface keeps your fingers secure during reloads, even when things get wet or sweaty. Chamfered edges mean no sharp corners digging into your hands or gear. At 64 grams, the extension itself is light enough that it won't noticeably shift your mag's balance, and the finished assembly sits at a practical height whether you're running a compact or full-size P320 frame.

Frequently Asked Questions
Will this mag extension work on my SIG P320 frame?
The extension fits both compact and full-size P320 frames when installed on their respective 15 and 17-round magazines. It does not fit 10, 12, or 21-round SIG P320 magazines. If you run an AXG, Wilson Combat, Icarus, or Agency Arms frame, the extension will fit but those frames may require modification to the magwell for reliable function. The extension works on the X5 Legion without magwell modification.
How long does installation take?
The Tyrant CNC NoBak plunger system is designed for tool-free installation in 10 seconds or less. You simply slide the extension onto the magazine base pad and it seats automatically. Removal is just as quick: press the retention plunger and slide the base pad off.
What's included in the box?
You receive the magazine extension and a 10% power spring, which is included to ensure reliable feeding and proper retention with the extended magazine.
Does the aluminum construction hold up in hard use?
Yes. The extension is CNC-machined from 6061 aerospace-grade aluminum, the same material trusted in firearms components across the industry. The aluminum is heavy enough to ensure positive mag drops while remaining lightweight in hand. Chamfered edges reduce wear on gear and hands.
