Reports From the Range and Field

In 2010, Glock began introducing new Generation 4 versions of their pistol lines. The .40 caliber Models 22 and 23 were first, followed by the 9mm Models 17 and 19. A few other models have been introduced since, including the 21, 32 and 34. The early Generation 4 9mms had a few function problems with light target loads, but this was resolved with a proprietary recoil spring assembly designed for the 9mm.
