Xtech Tactical MTX 17 +5 Features The MTX 17 +5 is engineered with leading edge technology developed over years of design iteration and real-world testing with insights gathered from Navy SEALs elite law enforcement and Border Patrol instructors across more than 10 000 rounds on dozens of platforms. Five points of engagement provide a secure rock-solid lock-up without the need for set screws or spring pins and the extended 17-7 stainless steel spring ensures consistent follower tension across the full extended capacity for reliable feeding from first round to last. The proprietary baseplate material delivers unmatched durability compared to standard polymer baseplates and the extension installs and removes in seconds for quick magazine swaps in the field or at the range. For duty and competition shooters who need a proven tool-free magazine extension built to the standards of the most demanding users the MTX 17 +5 delivers dependable performance. The external geometry of the MTX 17 +5 is purpose-designed to support fast magazine changes and a natural blind index allowing the shooter to orient the magazine without looking and maintain situational awareness during dynamic use. Texture tread pattern and side scallops work together for reliable grip and control with or without gloves and the improved ergonomics and tactile control enhance the overall handling experience without compromising magwell compatibility. The extension integrates seamlessly with Xtech s MAG 17-17 magazines and Glock factory 17-round magazines and is compatible with everything that accepts a Glock factory magazine. For Glock 17 owners who want a complete lifetime-warranted magazine extension that outperforms the competition in reliability ergonomics and ease of use the MTX 17 +5 delivers and it is available for sale at GrabAGun.
