Backed by over 20 years of experience, the Lone Wolf Arms DUSK19 Semi-Auto Pistol with Ameriglo Steel Sights represents the pinnacle of the Glock-pattern pistol. The DUSK19 sports a superbly crafted 17-4 stainless steel slide with black PVD finish, front and rear serrations, and an optics cut that accepts Trijicon RMR and Holosun 407/507/508 footprints. The slide is topped with Ameriglo steel sights. Within the slide is a precision 416 stainless steel barrel with the DUSK19 profile that reduces cycling time and enhancing wear resistance. The DUSK19's polymer frame features the optimal 19 grip angle, dual interchangeable backstraps (flat and round), and integrated grip panels with textured grips. The magazine well is flared for fast reloads and features a toe kick. The new flat enhanced trigger system delivers a 30% reduction in peak force for smooth and efficient shooting. Lone Wolf has spent 2 decades perfecting the aftermarket Glock, and now they've applied that expertise to a pistol of their own creation. The result is something special. And like any good boutique Glock, it's compatible with a wide range of OEM and aftermarket parts so you can customize it to your heart's content.
