This sweet little gun from Glock is a rimfire with the same exact frame size and profile as the Glock 19, which makes it a great training gun for any shooter who runs one. It’s a pure Glock: it uses a 10-plus-one configuration, it’s easy to load, and Glock spent a lot of time working on the G44′s functionality. At $430, the price is very competitive as an inexpensive trainer.
