The G45 draws a mix of enthusiasm and measured criticism from owners. Ergonomics come up often. The Gen 5 grip accommodates a wide range of hand sizes and most users find it comfortable to shoot for extended sessions.
Reliability is the main selling point people cite. The G45 runs consistently and holds up under varied conditions, which matters most to those buying it for defensive use. The 17-round capacity is a genuine advantage over compact alternatives, and it gets mentioned frequently alongside versatility across home defense, range use, and some concealed carry.
Customization is a draw for the GLOCK platform generally. Aftermarket sights, holsters, and trigger components are plentiful, and owners take advantage of that.
The size is the main sticking point. Despite the compact slide, the full-size frame makes it larger than some expect for daily carry, and a few users coming from smaller guns note the difference in bulk. Shooters transitioning from double-action triggers sometimes need time to adjust to the striker-fired system, though most report it becomes natural quickly with practice.
Overall the G45 is well-regarded as a do-it-all 9mm, not the smallest carry option, but a capable choice when capacity and shootability are the priority.
