Expert review

What makes the SUB-SDP stand out is Kel-Tec's folding sub design — it collapses for storage and transport, then deploys quickly.

The 9mm chambering keeps recoil mild and ammo cheap, so you can shoot it often without breaking the bank.

It fits shooters who want a compact, brace-equipped 9mm that's simple to stow and simple to run.
