X-Tech Magazine Extension

XTech Tactical, a company known for selling aftermarket magazines and extensions for some of the most popular firearms on the market, is now offering a +3 magazine extension for use with ten round 9mm magazines for the SIG Sauer P365 family of pistols.

The MTX 365 Magazine Extension turns a SIG Sauer P365 10-round magazine into a 13-round magazine while also providing additional grip area for the fingers of your hand. making the P365 easier to control during recoil. For nearly a decade now, slimmer 9mm polymer-framed, striker-fired pistols optimized around EDC (every day carry) have been and still remain one of the hottest market segments in the American firearms industry. The SIG Sauer P365 is one of the leaders in this segment, which inspired the design team at Xtech Tactical to develop additional support gear and accessories for these guns. 

“We set out to solve a problem no one else has [done so] in making multi round magazine extensions for the Sig Sauer P365. While extending the magazine capacity is one element, there was no solution that allows the shooter to maintain an ideal grip while using the standard sized P365 frame. When the user desires to shrink the platform down, they can now simply swap out their magazine versus swapping their pistol frame. We have no doubt that the market will find our newest extender to be the ideal option in the market for the standard P365 frame” stated Jeremy Deadman, the director of Sales And Marketing for XTech Tactical.

The base pad of the XTech Tactical MTX +3 P365 Magazine Extension is textured to provide the hand, palms and fingers with extra surface area and to aesthetically blend with the Sig Sauer P365’s frame. The extension is made of high-impact glass filled nylon 6 and and ships with a 17-7 stainless steel magazine spring. The magazine extension is made in the United States of America and retails for $19.95. Please visit for more information.
