The PTR 9LTR-CS – 9×19mm Rifle is a compact, rifle-configured evolution of PTR’s proven 9mm platform, engineered for reliability, control, and adaptability. Chambered in 9×19mm and operating via PTR’s legacy roller-delayed blowback system, the 9LTR-CS provides smooth recoil characteristics and consistent cycling compared to traditional straight-blowback designs. The rifle features a 12.5” nitride heat-treated barrel with a 1:10” right-hand twist, optimized for accuracy and durability. The barrel includes a 3-lug interface and 1/2×28 threading beneath a pinned and welded 3.5” muzzle brake, bringing the firearm into a rifle configuration while maintaining compatibility with common mounting standards beneath the device. This setup balances compact handling with compliance at the point of sale.
