Super Duty® MOD1-A Pistol, 8", 300 BLACKOUT - Black

The Super Duty® MOD1-A retains the proven performance and features of the Super Duty® MOD1 platform, while incorporating fully ambidextrous controls. Shooters now benefit from a system optimized for total control in the most dynamic shooting conditions. The MOD1-A utilizes the same intuitive layout used in Geissele’s GFR and MRGG rifles, trusted by elite professionals where efficiency and reliability are non-negotiable.

A magazine release on the left side of the receiver below the Maritime Bolt Catch makes mag changes swift for left-handed use. The right side of the receiver features bolt catch and release buttons below the ejection port. The shooter uses the dust cover to apply pressure to the bolt catch to lock the bolt open, and a release button just rearward easily sends the bolt forward. This instinctive system doesn’t just accommodate left- or right-handed use, but enhances mechanical flow under pressure. Reloads and malfunction clearances are faster and more consistent—critical when seconds matter. Whether on the move or on the bench, everything works in concert to meet real-world performance demands.

Setting the Super Duty MOD1-A 300BLK apart is the patented Phased Array® gas system, which utilizes Geissele Tri-Port™ System to precisely balance gassing and eliminate the need for an adjustable gas system. Combined with the Geissele braided buffer spring, this system provides a reliable and smooth shooting experience, whether shooting suppressed or unsuppressed with super or subsonic ammunition.

The Super Duty MOD1-A 300BLK includes the enhanced features foundational to the Super Duty MOD1-A platform that contribute to the industry leading performance, reliability, ergonomics and modularity, including:
