## What Customers Say

*AI-generated insights from customer reviews*

Owners of the Rex Zero 1S generally come away positive, though with some practical reservations.

The grip ergonomics get consistent praise, most find it comfortable through longer range sessions, and the overall size works well for both concealed carry and home defense. Reliability and accuracy at the range are the most commonly cited strengths, and the trigger pull is described as smooth enough for accurate work.

Aftermarket support is the main friction point. Holster options and other accessories are more limited than what's available for more established platforms, which matters to shooters who want to customize their setup.

Price comes up often in a favorable way. Most consider it competitive against other pistols in its class, making it an attractive option for those who want a capable DA/SA without paying a premium.
