Owners of the Kel-Tec Sub-2000 consistently cite the folding design as the primary reason they chose it. The ability to pack the carbine into a bag or case without disassembly is a practical feature that owners use regularly, and the Gen 2 improvements over the original get positive mentions.

The Glock 17 magazine compatibility is a frequently appreciated detail. Owners who already run Glock 17 pistols like that they can consolidate their magazine supply. Trigger feel is a common discussion point; the stock trigger is described as functional but not refined, and aftermarket options are widely discussed in owner communities.

At its price point, the Sub-2000 is generally seen as a good value for a folding 9mm carbine. Some owners note that the polymer construction has an economy feel compared to metal-framed alternatives, but most report that it runs reliably and holds up with regular use.
