What Makes a Glock Gun Different Than Any Other (Love It Or Hate It)
When Glock released the Glock 17, it reinvented the striker-fired pistol. While strikers saw some usage in early semiautomatic pistols like the Savage 1907 and Ruby, they largely faded into obscurity as hammer-fired designs came to dominate pistols design during WWII and in the immediate postwar era. H&K made a brief attempt to revive the striker with the VP70, a polymer frame striker-fired pistol that came before the Glock, but the striker design in the VP70 resulted in a horrendous trigger pull and limited the success of the pistol.
However, Glock implemented a new way of implementing a striker-fired trigger. Not all striker-fired pistols are the same. The Savage 1907 used a pseudo-hammer to draw the striker back, where it could be released, resulting in a very short and light trigger pull. However, this design required a manual safety to hold the striker in place to be carried safely.
Conversely, the VP70’s trigger drew the striker back and released it in the same pull. As the operator was fighting the strong striker spring during the trigger pull, it was notoriously heavy and made the pistol unpopular. However, the trigger was fairly safe.
Glock’s trigger combines the two aspects and increases the safety of the design. The striker is partially cocked via the first few millimeters of rearward movement of the slide. Once cocked, the striker is locked by the striker safety, which prevents the firing pin of the striker from protruding from the bolt face.
