Xtech Tactical Magazine for Glock 17 Gen 4 Features The Xtech Tactical Magazine for Glock 17 Gen 4 is built around a steel-reinforced magazine body that adds durability well beyond what the factory polymer magazine offers. An upgraded 17-7 stainless steel spring replaces the factory spring providing more consistent spring tension over the life of the magazine and reducing the chance of feeding issues as the magazine ages. A proprietary baseplate material is paired with a Delrin No Stick follower which is designed to reduce friction as rounds feed keeping the action running smoothly even under hard use. Holding 17 rounds this magazine matches factory Glock 17 capacity while delivering meaningful upgrades in durability. Because it is compatible with everything that fits a Gen4 Glock factory magazine this Xtech Tactical magazine drops straight into existing pistols mag pouches and accessories without requiring any other changes. The steel-reinforced body resists the wear and minor deformation that can occur with repeated use of a standard polymer magazine over time. Made in the USA this magazine is built to a standard that appeals to shooters looking for a durable upgrade rather than a simple replacement part. For Glock 17 Gen 4 owners wanting more longevity from their magazines this steel-reinforced option is a straightforward upgrade.
