"It's more than ""just"" another GLOCK 19 clone. The Lone Wolf Arms Timberwolf 19 Optics-Ready Semi-Auto Pistol is the result of decades of aftermarket expertise producing the finest GLOCK-compatible accessories. It's built atop the Timberwolf compact frame, featuring a relieved-radius beavertail for high grip, undercut trigger guard, enlarged controls, and a more natural grip angle. Interchangeable back straps allow for easy customization to fit your palm size. The slide is made from heat-treated 17-4 stainless steel machined by Lone Wolf, and features an optics cut for Trijicon RMR footprints. Top, front, and rear slide serrations improve slide control, and Night Fision lower 1/3-height sights create a brighter sight picture, day and night. The barrel is also made from heat-treated 416 stainless steel and black nitride-coated for corrosion resistance. The shallow-recessed crown ensures symmetrical interface between bore and muzzle for improved accuracy, and the chamber is capable of firing lead, plated, and jacketed ammo. Finishing the package is Lone Wolf's Enhanced Flat Trigger, delivering a 30% reduction in peak force for a smoother pull. Compatible with most GLOCK double-stack magazines.
