• Fixed 3-dot steel sights for quick target acquisition without the added cost of an optic.

• Single/double action trigger operation, giving a heavier first pull and a lighter reset for follow-up shots.

Owners of the Zero 1 Compact tend to praise the fit and finish of the aluminum frame and nitride slide, noting smooth cycling and a trigger that feels tighter than many striker-fired guns in this size class. Shooters new to Arex approach the brand cautiously since it lacks the long track record of bigger names, but most come away confident after a range session or two.

The compact frame and FDE finish make it a popular pick for concealed carry, and the polymer grip panels get good marks for control even though the metal frame adds some weight over an all-polymer compact. The factory 3-dot sights are functional, though a few owners swap them for night sights right away.

Buyers generally see the Zero 1 Compact as good value against pricier European imports, though holster and aftermarket accessory options are still catching up to more established compact 9mm platforms. Owners who stick with the factory setup report few complaints, while those hunting for a deep aftermarket ecosystem sometimes look elsewhere.
