NineX19 was founded with the simple mission of engineering and manufacturing premium quality firearm parts and components for discerning enthusiasts while offering them at a price that provides maximum performance per dollar. NineX19's primary focus is on match-grade pistol barrels and slides for popular Glock and SIG platforms, but we also apply our decades of collective engineering expertise and machining capability to our full line of sights, magwells, triggers, parts kits, and more.
