when did the glock gen 2 come out
Glock Glock has updated its basic design several times throughout its production history. A mid-life upgrade to the Glock pistols involved the addition of checkering on the front strap and serrations to the back strap. These versions, introduced in 1988, were informally referred to as "second-generation" models. To meet American ATF regulations, a steel plate with a stamped serial number was embedded into the receiver in front of the trigger guard. 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.
