The KelTec SUB2000 Gen 3 in 9mm is a semi-automatic carbine that folds in half and accepts Glock 17 and Glock 19 magazines (brand part no. SUB2K9GLKBLKCA). KelTec built the third generation with a rotating forend, so an optic can stay mounted when the carbine is folded. A 16.15-inch barrel gets more velocity out of pistol ammunition than a handgun can, and the straight blowback action is simple to run and maintain. It can be disassembled for cleaning without tools, and KelTec positions it for backpacking trips and other situations where space and convenience matter.
