Product Evolution
Glock has updated its basic design several times throughout its production history. Commentators had long separated the large changes into generations. Glock eventually accepted this nomenclature with their "Gen4" models.
In 1991, an integrated recoil spring assembly replaced the original two-piece recoil spring and tube design. The magazine was slightly modified, changing the floorplate and fitting the follower spring with a resistance insert at its base.
