Built on the Glock 19X crossover format, this collaboration pairs Agency Arms custom work with Sage Dynamics branding. The coyote slide is custom-machined with front and rear serrations, top "SAGE" engraving, and the Sage Dynamics crest/logo alongside AGENCY branding. The coyote polymer frame carries extensive Agency enhancements for control and ergonomics.
The Holosun HS507C X2 red dot is installed and ready, bringing a red Multi-Reticle System (2-MOA dot / 32-MOA circle-dot), Solar Failsafe, and Shake Awake in an open-reflex design. This optic setup delivers immediate sight acquisition and flexible reticle options out of the box.
A threaded barrel with an Agency Arms compensator is installed, extending overall length beyond the factory 4.02-inch barrel specification. A flat-faced trigger shoe, double undercut trigger guard, frame stippling, and forward index pads support a consistent grip and straight, repeatable trigger press.
Glock 19X features remain intact, including ambidextrous slide stop levers, reversible magazine release, a lanyard loop, and the G17-length grip that supports 19+1 capacity. Markings include "Made in Austria / Glock, Inc., Smyrna, GA" on the frame mold line, noting its Austrian origin with Glock U.S. distribution.
