The SUB-SDP "Nub Sub" distills the iconic folding-carbine platform into pistol form, delivering the most compact configuration the SUB2000 has ever taken. An integrated pistol stabilizing brace transforms shootability without sacrificing the platform's signature compactness. The handguard also includes a 1913 Picatinny accessory rail for mounting optics along with M-LOK accessory slots and a threaded barrel to allow for a wide degree of customization. When stowed the handguard can be rotated to allow for seamless stowing even with an equipped optic. This model is chambered in 9mm Luger and features an angled magazine holder. Two 27-round magazines are included.
