XTech Tactical MTX Magazine Extension Features The Xtech Tactical MTX Magazine Extension is engineered with five points of engagement to lock securely onto the factory Glock 43 magazine body preventing wobble or disconnection during use. An extended 17-7 stainless steel spring replaces the factory unit providing the added length and tension needed to reliably feed the additional five rounds. The proprietary baseplate material is formulated specifically for this application giving the extension durability that holds up to repeated loading unloading and daily carry. Together these components turn a standard capacity Glock 43 magazine into a higher capacity option without changing the magazine s overall reliability. Compatible with Gen3 through Gen5 Glock 43 pistols as well as many compatible clone platforms the MTX extension fits virtually anything that already accepts a Gen4 Glock factory magazine. This broad compatibility makes it a practical upgrade for shooters running a range of similar pistols. Made in the USA the extension is built to the same quality standards shooters expect from a dedicated magazine accessory manufacturer. For Glock 43 owners who want more rounds on tap without switching magazines entirely the Xtech Tactical MTX Magazine Extension delivers a simple durable capacity boost for sale at GrabAGun.
