This Is Why the Glock Stands Above All the Rest

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.

When the trigger is pulled, the trigger cocks the striker back slightly further, while the trigger bar depresses the striker safety to release it. The trigger safety on the trigger enables this rearward movement. At a certain point, the trigger bar’s sear drops the striker and allows the pistol to fire. The movement of the slide resets the striker, and the cycle is repeated the next time the trigger is pulled.

This system of a “pre-cocked” striker allowed for a short, light trigger pull similar to most hammer fired single action guns, but with the additional inbuilt safety mechanisms most traditional single action guns lacked.

Similar pre-cocked strikers are present in almost every other polymer-framed striker-fired pistol, with minor changes to avoid infringing on Glock’s patent. H&K’s VP9, for example, features a rotating striker safety instead of a button-style one on the Glock. It also features a sear separate from the trigger bar, which holds the striker in a cocked position prior to release.

In the early days of the striker polymer pistol revival, some companies produced pistols with older-school double action striker triggers like the FN Forty-Nine, which featured a VP-70 style system that cocked and released the striker with a “double action” trigger pull. Walther also released a version of the P99 with a “double action” trigger, but it didn’t receive many sales. These pistols featured the ability to “second strike” a round that failed to ignite on the first shot, a capability that double action and double action/single action hammer fired pistols have.

While this may have been considered to be a feature in the 1990s, modern training rarely emphasizes second-strike capability, in favor of racking the slide to remove the misfiring round to quickly get the pistol back into action instead of gambling that it will discharge on a second strike.
