Product information

US-221 Duty Holster — RDS-Compatible with SRS Internal Lock

The US-221 is a professional duty holster designed for officers carrying slide-mounted red-dot sights. It features the SRS Safety Retention System™ for secure internal locking and a responsive thumb-release for fast, controlled draws—ideal for agencies standardizing on RDS-equipped service pistols.

Retention & Performance

  • SRS Safety Retention System™ — internal auto-lock that secures the pistol when holstered and releases via an ergonomic thumb action.
  • Passive tension screw — fine-tune retention to match departmental requirements and carrier preference.
  • Designed to deliver a predictable, gross-motor draw suitable for duty use.
