The PTR Industries 9SD Integrally Suppressed SBR brings the classic roller-delayed 9mm platform into a modern, ultra-quiet configuration. Built around a compact 4.58" barrel with integral suppression, it delivers smooth cycling and reduced report while maintaining the familiar HK-style ergonomics and control layout.

This short-barreled rifle is purpose-built for shooters who want a controllable, soft-recoiling 9mm carbine for training, range use, or practical defensive applications where a compact footprint and reduced noise are priorities. The integrally suppressed system and velocity reduction device help keep standard 9mm loads comfortable to shoot, while PTR Industries’ attention to detail and proven roller-delayed design support long-term reliability and consistent performance.
