9SDM 9MM Integrally Suppressed SBR – CS1 Collapsible Stock

The PTR 9SDM brings modern suppressor technology to the iconic MP5SD-style platform. Built on PTR's proven roller-delayed blowback operating system, the 9SDM is a factory-configured, integrally suppressed 9mm short-barreled rifle engineered for exceptional sound reduction, smooth recoil, and reliable performance.

At the heart of the 9SDM is a specially engineered 6-inch ported barrel designed to reduce standard supersonic ammunition to subsonic velocities. Unlike traditional SD-style barrel designs, PTR positions the ports within the rifling grooves to help prevent bullet-jacket damage, reduce fouling, and simplify maintenance.

The 9SDM also introduces PTR's Universal SD Adapter (USDA), a pre-suppressor system that captures and slows high-pressure gas before it reaches the suppressor. This innovative design supports both HUB Alpha and HUB Bravo mounting interfaces, providing additional flexibility.

Advanced Suppressor Technology

The PTR 9SDM is offered with two suppressor configurations:

• PTR VENT 2: A versatile, low-back-pressure titanium suppressor utilizing a HUB Alpha mounting interface. Designed for excellent sound suppression while maintaining compatibility with other supported platforms.

• PTR VENT SDM: Purpose-built specifically for the 9SDM, utilizing a HUB Bravo mounting interface and optimized for maximum sound suppression, balance, and compact handling.

Both suppressors feature 3D-printed titanium construction, PTR's proprietary Purposely Induced Porosity (PIP) technology, and a protective DLC coating.
