The PTR Industries PTR 9SDM-B is an integrally suppressed, semi-automatic 9mm short-barreled rifle that pairs the classic MP5-style profile with modern upgrades. It’s built around a 4.58" ported barrel and the dedicated PTR Vent SDM suppressor, so it runs quiet and smooth while keeping the familiar feel of a roller-delayed action. A 13.2" steel Picatinny rail, a removable aluminum M-LOK handguard, and a collapsible Magpul MP5-style stock make it easy to add optics and accessories.

This SBR is built for shooters who want suppressed performance for range use, training, and home defense, where low noise and controllable recoil matter most. The ported barrel bleeds off gas to keep velocities down and reduce fouling, which makes cleaning easier and keeps performance consistent through long sessions. With its integrated design and compact 22.75" collapsed length, the 9SDM-B shows PTR’s focus on reliability and refined craftsmanship in the roller-delayed platform.
