Analysis

The Standard model was the first U.S. Arex pistol, imported for the 2016 SHOT Show as an aluminum-frame alternative to the SIG P226 with a list price near $650. It uses 17-round steel magazines and a one-piece cold-hammer-forged barrel; Arex cited high endurance-test round counts before release. Compact and Tactical versions and the steel-frame Alpha followed from the same family. Import passed from FIME Group to Global Ordnance around 2020. The later Zero 2 S revises the grip and magazine release, but the original S remains listed. Used examples commonly sell from the high $200s into the low $500s depending on finish and extras.
