The Tyrant CNC P365 X-Macro extension gives you three extra rounds without adding bulk or weight to your carry gun. It's machined from 6061 aerospace-grade aluminum and finished in gray anodize that'll hold up to daily carry while keeping things looking clean and professional. The dimensions are tailored to match the P365 X-Macro frame so it stays low-profile and won't print through your clothes.
What sets this extension apart is the NoBak retention plunger technology. Instead of fumbling with tools or complicated assembly, you just push the plunger in and slide the extension onto your magazine. The whole install takes about 10 seconds. When you need to remove it, a quick push and it comes right off. This means you can swap mags around or clean your magazines without any fuss. The retention is rock solid too, so dropping your mag on concrete won't rattle anything loose.
The machined aluminum construction keeps things lightweight while still being tough enough for repeated use. Unlike some extensions that need a power spring upgrade to function, Tyrant engineered this one to work with your existing magazine spring. That said, the extension comes with a replacement spring if you need it. The profile is specifically designed to minimize printing when carried, which matters if you're trying to keep a discrete carry footprint. For range days or defensive use, you get that extra capacity without the bulk of an extended grip module.
Yes, this extension is designed exclusively for Sig Sauer P365 X-Macro 17-round magazines. It will not fit the smaller P365, P365X, or P365XL magazines with inward-folding flanges. Make sure you have the correct 17-round X-Macro magazines before ordering.
Installation is genuinely tool-free and takes about 10 seconds. You just push in the NoBak retention plunger and slide the extension onto your magazine's bottom. Removal is just as easy. The extension includes a replacement spring, but it can function with your factory spring depending on production date.
This depends on when your magazine was manufactured. Some earlier production OEM Sig springs may not have enough tension to hold the slide back when paired with the extension. If you experience this, the included replacement spring should resolve it. It's a known issue across all P365 X-Macro extensions due to supplier changes Sig made on the OEM magazines.
The extension is dimensioned to match the P365 X-Macro frame for minimal printing. Added weight is minimal since it's made from lightweight aerospace aluminum, and the profile stays compact enough for concealed carry. Many users report it integrates cleanly into carry setups without changing how the gun sits in a holster.
