The heart of this Erebus is its 4.6-inch bull barrel paired with a single-port compensator for controlled recoil management. The tri-top slide with extensive lightening cuts reduces reciprocating mass, and the full-length dust cover adds forward weight and integrates an accessory rail.
The 2011-pattern double-stack steel frame uses an aggressively textured aluminum grip module with interchangeable panels and an extended, flared magwell. Controls include an ambidextrous thumb safety and a grip safety. The trigger is flat-faced, tuned, and lightweight at under 2 pounds with an overtravel screw.
This pistol is configured for a slide-ride optic with no iron sights and comes equipped with a Trijicon RMR HD red dot featuring a 1.0 MOA aiming point. The setup is marked 'Perfect Zero' on the chamber hood and carries factory rollmarks: 'ATLAS GUNWORKS INC. • USA • SHELBURNE, VT.' and '9MM'.
Capacity is 20+1 with the included high-capacity magazines. Unloaded weight is about 39.5 oz (factory spec). The build is U.S.-made in Shelburne, Vermont, and the accessory rail on the full-length dust cover supports light or laser attachments as desired.
