The DB9 Gen 4 pairs a black polymer frame with molded textured panels and a matte black slide cut with front and rear cocking serrations. The micro-size profile is complemented by a mild beavertail and an undercut trigger guard for an efficient, compact grip.

The sight system uses Glock 42/43-pattern dovetails. The front is a blade with a colored dot, and the rear is a drift-adjustable square-notch retained by a set screw, allowing secure positioning once zeroed.
Capacity is a single-stack 6+1. The included OEM steel magazine is manufactured by ACT-MAG (Italy) and features a Diamondback shield baseplate with a finger-extension for added purchase.
Rated by the manufacturer for SAAMI-spec +P ammunition, this Gen 4 DB9 is made in the USA and configured for dependable use in a compact 9mm format.
