The Glock G45 Gen6 is a striker-fired 9mm Luger pistol that pairs a compact-length 4.02-inch barrel and slide with a full-size frame. It uses Glock's Safe Action system and ships with an optics-ready slide for mounting a red dot, along with three included optic plates. This crossover configuration is built for shooters who want full-size grip control with a shorter slide.

The Glock 45 line has a loyal following built on Glock's reputation for running reliably with minimal maintenance, and the Gen6 update carries that reputation forward. Owners of the optics-ready G45 Gen6 tend to praise how easily a red dot mounts using the factory plates without needing a separate adapter plate purchase.

Ergonomics get more attention than usual for a Glock, since the redesigned grip texture, palm swell, and beavertail are a noticeable departure from earlier generations. Some longtime Glock shooters need a few range trips to adjust to the flat-faced trigger and deeper slide serrations, while others prefer the new feel immediately.

On value, the G45 Gen6 sits toward the pricier end of the Glock lineup because of the added optics-ready cut, but owners generally see that as fair given how much aftermarket support and holster compatibility exists for the platform. The crossover size, a full-size grip with a shorter slide, is frequently mentioned as the reason buyers pick this configuration over a standard full-size or compact model.
