The G17L platform delivers the hallmark long-slide configuration with a 6.02 inch barrel, a lightening window in the slide, and a sight radius of approximately 8.03 inches. These features support the model’s competition-oriented role while maintaining Glock’s proven reliability.
This example is customized with fiber-optic sights — a red front and green two-dot rear — for quick, high-visibility alignment. It also features an upgraded trigger, providing a distinct feel compared to a standard unit.
The Gen 3 polymer frame includes integral finger grooves and a single-slot accessory rail. It is a striker-fired design with Glock’s Safe Action system. Capacity is 17+1 rounds using the included factory magazine.
Markings include "MADE IN AUSTRIA / GLOCK, INC., SMYRNA, GA" on the pistol. The slide bears an additional alphanumeric stamping forward of the ejection port, and the slide is noted as not original to the frame — details that help identify this specific build. The steel barrel and the long slide configuration are defining elements of the G17L line, which has been produced in limited batches over time.
