CMMG Dissent Mk4 9mm 5.5" 30-Round Threaded Barrel Pistol

The CMMG Dissent Mk4 9mm 5.5" 30-Round Threaded Barrel Pistol is a modern, modular platform built for operators who demand reliability and configurability in a compact package. Designed for tactical professionals, home defenders, and serious shooters, this pistol combines the proven 9mm cartridge with CMMG's engineering excellence. The threaded barrel accommodates suppressors or compensators, making it an excellent choice for shooters who value noise reduction, recoil management, or both in high-stress environments.

Built with precision machining and robust materials, the Dissent Mk4 features a 5.5-inch threaded barrel that provides superior velocity and ballistic performance compared to shorter defensive pistols while remaining highly concealable. The 30-round capacity offers extended engagement capability without magazine changes—critical in sustained-fire scenarios or force-on-force training. The Mk4 platform demonstrates CMMG's mastery of modular design, allowing users to swap components, adjust ergonomics, and customize the firearm to match their specific mission requirements. Its manageable recoil impulse and consistent trigger control make follow-up shots fast and accurate.

This pistol benefits law enforcement, military personnel, armed security professionals, and civilian tactical shooters who integrate suppressors into their duty or training loadout. The threaded barrel's 1/2x28 standard thread pitch is compatible with most commercial 9mm suppressors, making sound signature reduction straightforward. At approximately 1 pound unloaded, the lightweight profile reduces operator fatigue during extended operations. Whether mounted with a suppressor for low-signature work or run unsuppressed for maximum velocity, the Dissent Mk4 delivers consistent performance across diverse operational contexts.
