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 brace transforms shootability without sacrificing the platform’s signature compactness. The SUB-SDP is the first pistol variant of the iconic SUB2000, KelTec’s signature folding carbine that has defined the pistol-caliber carbine category for over two decades. Same reliability. Same folding functionality. Same KelTec engineering. Distilled into the most compact configuration the platform has ever taken. Every SUB-SDP ships with an integrated pistol brace, delivering control and shootability that transforms the pistol platform. Faster follow-up shots. More precise fire. The compact footprint stays compact. An integrated M-LOK rail provides accessory attachment points for lights, lasers, and mission-specific gear. Every SUB-SDP is built to be configured for the way you carry, shoot, and defend.
