Atlas Gunworks Erebus v3
The Erebus v3 is Atlas Gunworks’ light, compensated, slide-ride-optic pistol built for Open Class 3-Gun competition — a gun that can still be carried in a retention holster, which a frame-mounted Open gun cannot. Atlas calls it the fastest-cycling, flattest-shooting platform in the world, and Honest Outlaw and Manzano Tactical have both put the Erebus v3 on camera.
It pairs a 4.6-inch threaded bull barrel and compensator with a 7 lb recoil spring, the lightest in the current lineup, on the v3 Perfect Zero platform: Vermont-machined billet slide, v3 optics plate, Glock-style front sight and patent-pending angled grip bushings. Weight is 38.11 oz without a magazine.
Cajun Gun And Gear is the only authorized Atlas Gunworks dealer in Louisiana. Erebus v3 pistols in stock are listed below; call 337.999.0373 to order a configuration you do not see.

Who the Erebus v3 is for
3-Gun and Open-division shooters who want a comped 2011 with the dot on the slide, and anyone who wants the softest-shooting Atlas for the range. The ported Apollo v3 is the closest alternative without a compensator, and the sight-block Artemis v3 is the non-comp Limited Optics choice.

Atlas Gunworks Erebus v3 FAQ
What is a slide-ride optic?
The red dot mounts to the slide (via the v3 plate) and reciprocates with it, instead of sitting on a frame mount. It keeps the gun compact enough for a retention holster.
Why does the Erebus v3 use a 7 lb recoil spring?
The compensator bleeds gas and slows the slide, so Atlas tunes the Erebus with the lightest spring in the lineup for reliable cycling with factory 9mm.
How much does the Erebus v3 weigh?
38.11 oz without a magazine.
Can I carry the Erebus v3?
Atlas notes it can be carried in a retention holster; most owners treat it as a competition pistol.
