The KelTec SUB-SDP 9mm in tan takes the SUB2000 folding format and turns it into a braced pistol with a 6-inch threaded barrel (KelTec part no. SDP9TAN). Known as the Nub Sub, it is the shortest layout the platform has had, and it folds to a 10-inch package for storage. The finish is tan, and an integrated brace sits at the rear of the frame to steady the gun. With an M-LOK rail up front and a threaded muzzle, it is set up for a light, a laser or a muzzle device. It is a practical choice for truck guns, range trips and home use.

Key Specifications

• Magazine capacity is 17 rounds, plus one in the chamber, so the pistol holds a 17+1 load for long strings of fire.
• The chambering is 9mm, a widely available cartridge that keeps practice affordable.
• Barrel length is 6 inches, longer than most pistols in this caliber, which adds sight radius and muzzle velocity.
• Barrel threads are 1/2-inch-28, the common 9mm pattern that fits many compensators and muzzle devices.
• Overall length is 17.7 inches extended, compact for a pistol with a barrel this long.
• Folded, the pistol measures 10 inches, which makes it easy to stow in a pack or under a seat.
• Unloaded weight is 3.57 pounds, so it stays light through a long day of shooting.
• The finish is tan on a polymer build, which resists corrosion and keeps weight down.
• The pistol includes an integrated brace, which adds stability and control from such a small frame.
• Width is 1.94 inches, slim enough to slide into a bag without bulk.

Frequently Asked Questions

Is the barrel on the tan SUB-SDP threaded? Yes. The 6-inch barrel is threaded 1/2-inch-28, the standard 9mm muzzle thread, so muzzle devices cut for that pattern will mount.

What accessory mounting does it offer? KelTec builds in an M-LOK rail on the SUB-SDP for attaching lights, lasers and other gear.
