Our MTX 365 +3 provides a significant grip improvement for the SIG Sauer P365 micro compact pistol, offering a superior alternative to factory magazines and even the larger X/XL grip modules. This extension kit transforms the standard P365 into the extended grip length of the P365X/XL without compromising style or functionality. Made in the USA, this patented magazine extension is 100% reliable, ensuring enhanced control and a more secure grip. The SIG P365 Mag Extension is designed for factory 10-round magazines compatible with standard P365 and Wilson Combat P365 frames, but it is not intended for 12-round or 15-round magazines or for use with P365X, P365XL Or P365 Macro frames. With a unique design that integrates seamlessly with the P365 platform, this extension works on Sig magazine bodies featuring inward facing tabs where other extenders fail. The custom engineered spring ensures unmatched reliability and guarantees last round bolt hold open. Installation is made easy with a QR code linking to a detailed video guide. This extension enhances the shooting experience by providing the perfect pinky extension for increased tactile control, improving grip and precision without requiring an XL frame.
