The Tyrant CNC P365 X-Macro magwell is a precision-machined aluminum accessory built to speed up magazine changes on your Sig Sauer P365 X-Macro. If you carry a P365 X-Macro for everyday defense, competition, or range work, this magwell replaces the factory grip module bottom with a flared, funneled design that guides the magazine home faster and more reliably—especially under stress or in low-light conditions where fumbling costs you time you don't have.
Tyrant CNC engineered this magwell specifically for the P365 X-Macro 17-round magazine and frame after reverse-engineering the grip module to ensure a snug fit without requiring any gunsmithing. The aluminum construction is CNC-machined to tight tolerances, yet built with enough tolerance to accommodate minor variations in grip module molding. It mounts to your existing grip module using a supplied screw and nut—no permanent modifications, no fitting headaches.
The slim profile is designed to disappear under a concealment garment without printing, so you don't sacrifice concealed-carry suitability for reload speed. Beyond the magazine funnel, the magwell adds usable grip surface area—giving your pinky a ledge and providing a solid platform to manage recoil with better leverage. The aesthetics are refined and match the X-Macro's lines, so it looks like it came from Sig.
If you're running your P365 X-Macro as an EDC gun, a match pistol, or a duty backup, faster reloads mean fewer seconds of vulnerability when you need them most. This is the kind of upgrade that sounds simple—bigger funnel, faster reload—but compounds across hundreds of repetitions at the range and could matter in a real situation.
