The impossible-to-own-legally Glock 18 and the we-can’t-have-nice-things-because-of-our-stupid-import-laws Glock 25 are the two guns most Glock collectors will never have in their collections. Of the weapons that mortals can own the Glock 17R may be at the top of the list. The “R” refers to the automatic trigger Reset. This allows the shooter to practice dry firing on a gun that looks and feels like a real Glock. But the gun’s design means that it can’t actually chamber and shoot a live round. Sounds great, right? I’ve learned that the 17R isn’t quite the training pistol nirvana that it’s cracked up to be.
