Quick Overview now offers the G3 trigger, another addition to our huge rollout of original, Heckler & Koch G3 replacement parts and accessories. As everyone knows, the trigger is one of the most vital components of a firearm. A little later, you will find out how it works and why it is more than just “the thing that makes a gun go boom.”

In general, a trigger is the name given to any device that serves as a catalyst that elicits a reaction or series of reactions. In the case of a firearm, the trigger is the device that initiates the firing sequence. Our G3 trigger is an original HK part, specifically manufactured to work with the G3’s trigger housing, sear and hammer.

Without a trigger, your G3 will not fire. Make sure you’re never in a position that will have your rifle out of commission and order the G3 trigger today for only $4.95.

Chain Reaction

The function that a firearm’s trigger serves is actually a quite simple concept. To understand the chain reaction that a trigger initiates, one must be familiar with a few key components, including: the trigger, sear, hammer and firing pin. The sear is a part of the trigger mechanism that holds back the hammer, which is a device under spring-tension that, when released, strikes the firing pin. When enough pressure is applied to the trigger, it will manipulate the sear in a way that releases the hammer, which in turn will strike the firing pin, igniting the primer and discharging the firearm.
