Glock G45 Gen5 9mm - Ported, Custom Optics-Cut Slide, Timney Trigger, 17+1, 4.02 in Barrel
This customized Glock G45 Gen5 stands out with a ported configuration, a slide professionally milled for an optic with a cover plate, and a Timney aftermarket trigger. It uses the G45 crossover layout (G19-length slide on a G17-size frame) and combines a USA-marked frame with Austrian-marked slide and barrel. Non-matching serial numbers between the frame and slide/barrel are noted, adding clear provenance for buyers who track components.

The G45’s crossover design pairs a compact-length slide with a full-size frame, giving it a 4.02 in barrel and 17+1 capacity. Gen5 updates include an ambidextrous slide-stop lever, a flared magwell, and a reversible magazine release. It wears a black nDLC slide finish with front and rear cocking serrations and fixed sights (white-dot front, notch rear).
Custom work features a slide milled for an optic and secured with a screw-retained cover plate, plus top window lightening cuts. This example is set up in a ported configuration. The Glock accessory rail is present for lights or other rail-mounted equipment.
A Timney aftermarket trigger is installed, featuring an aluminum shoe and a red safety blade. The trigger upgrade offers a distinct feel compared to the factory unit while preserving Glock’s Safe Action system.
The 4.02 in Glock Marksman Barrel incorporates revised rifling and a revised crown. The barrel hood carries an "AT" mark and a pentagon "5" stamp. The frame is marked "MADE IN USA," while the slide and barrel are Austrian-marked. Non-matching serial numbers between the frame and slide/barrel are documented.
