Why the Glock 45 Gen5 Stands Out
Having tested this pistol alongside dozens of competitors on our Spring TX range, the Glock 45 Gen5 delivers what matters most: consistent performance when your life depends on it. The hybrid G17 frame/G19 slide configuration gives you better control than compact models without sacrificing concealability.

Who Should Buy This
Buy it if: You need a duty-ready 9mm that disappears under a jacket, want Glock reliability without finger grooves, or need a pistol that transitions seamlessly from range to carry.
Skip it if: You require an optics-ready slide (see G45 MOS) or prefer a subcompact for deep concealment (check G43X).
Frequently Asked Questions
Is the Glock 45 Gen5 good for concealed carry?
Yes – the compact slide reduces printing while the full-size grip improves control. Carries easier than a G17 but shoots more comfortably than a G19.
What’s the difference between Gen4 and Gen5?
Gen5 removes finger grooves, adds ambi controls, and features the Marksman barrel. The trigger is slightly improved with a smoother break.
Does this include night sights?
No – it ships with standard polymer sights. We recommend upgrading to Trijicon HDs for low-light use.
Where can I buy Glock pistols online?
F1Firearms (f1firearms.net) ships Glocks to your local FFL with same-day processing from our Flagstaff warehouse.
What holster fits the G45?
Any holster made for Glock 19/17 Gen5 will work – the G45 uses the same holster as a G19 but with G17 grip length.
Is the magazine compatible with other Glocks?
Yes – these 17-round mags work in any double-stack 9mm Glock (G17, G19X, G34). Won’t fit single-stack models.
Why is your price lower than MSRP?
We buy direct from Glock in bulk and pass the savings to customers. This is a new pistol with full factory warranty.
