Double Diamond Hex Fire: The Pinnacle of Nashville Custom Machining
The GlockStore state-of-the-art machine shop in Nashville, TN, is now fully operational, bringing world-class custom slide design to the heart of Tennessee. Our flagship Double Diamond Hex Fire slide represents the perfect marriage of aesthetics and performance, featuring our most aggressive porting in a visually striking hexagonal pattern designed to reduce weight and improve cycling speed.
