## What Customers Say

*AI-generated insights from customer reviews*

The Glock 45 platform carries Glock's usual reputation for running reliably with minimal maintenance, and Gen5 owners often point to the polygonal rifling and revised chamber as a small but real accuracy improvement over older generations. The most common complaint is trigger feel out of the box, which many owners address with an aftermarket trigger.

Ergonomics get good marks. The crossover format, a shorter slide on a full-size frame, gives a full firing grip while staying easier to conceal than a full-length duty gun, and the interchangeable backstraps let owners tune the fit to their hand. The MOS cut is popular for mounting a red dot without sending the slide out, and having the EoTech already mounted saves that extra step.

On value, the G45 Gen5 MOS sits at a premium next to a base Glock, but owners generally see the included optic and MOS compatibility as worth the price gap. Aftermarket parts, holsters, and sights are as plentiful as for any Glock, which keeps long-term customization simple.
