Mister Guns, a gun retailer based in Plano, Texas, experienced an external system breach due to hacking on November 14, 2025. The company discovered the breach on February 25, 2026, and notified consumers on March 31, 2026. This incident was confirmed by a filing with the Maine Attorney General in April 2026.
The breach affected 21,225 individuals in total, including 7 Maine residents. The compromised data included personally identifiable information (PII) and various government-issued IDs. While a ransomware group claimed responsibility and alleged exfiltration of 290GB of data, there is currently no evidence that the stolen data has been misused. The company did not offer identity theft protection services.
Breach details can emerge over time, and consumer notifications may be delayed.
