The EOS began as a steel-frame variant of the popular Ares 4.25, gaining roughly six extra ounces that translate to noticeably softer recoil and flatter tracking. That weight advantage, combined with aggressive slide and barrel porting, earned the pistol its Perfect Zero designation for near-zero muzzle rise.
Its 4.25-inch stainless bull barrel features three forward ports and a flush crown, while the optic-ready slide carries matching ports and an RMR/SRO “R2” footprint with integral recoil lugs for secure red-dot mounting.
The DLC-nitride-finished steel frame wears a full-length Picatinny dust-cover rail and an aluminum grip module with raised triangular texturing, ensuring both accessory flexibility and a locked-in hold.
A factory-tuned, flat-faced skeletonized trigger breaks cleanly at 3 pounds. Ambidextrous thumb safeties, a skeletonized rowel hammer, and fully adjustable rear sight with fiber-optic front round out a competition-ready control set.
Each Perfect Zero ships with six 15-round magazines and arrives in an Atlas soft case, giving the buyer a complete, range-ready package straight from the factory.
