Expert review

The appeal of the SUB-SDP is practicality: it folds down small, weighs very little, and runs affordable, common pistol magazines.

In 9mm it's soft-shooting and easy to handle, which makes it approachable for a wide range of shooters.

As a packable truck or pack gun, or a fun, low-cost range companion, few compact 9mms match its footprint.
