The trigger

The Trigger is a specialised mechanism of highly machined and finely tuned parts. It holds or locks the striking or firing mechanism in place, such as the hammer or internal firing pin.  When the shooter chooses to fire, the trigger mechanism will release the hammer, which in turn shall hit the firing pin or fire the cartridge directly. The Trigger mechanism evolved from being hand held- to an electrically operated system. Most Trigger systems basically operate in the same way: when releasing the hammer or firing pin of a pistol it will also release an large amount of kinetic energy stored in its springs. This in turn does affect the balance and position of the pistol when it is fired. For that reason the gunmakers of the 18th, 19th and 20th century started designing lighter and lighter operated trigger systems. The most common ones consisted of a single lever or a double set system. With the double set system the hammer is cocked and the trigger is set, which allows the shooter to fire the pistol with only the slightest touch of the second trigger. Many different gunmakers designed better and lighter systems as they progressed. Most systems use levers and are powered by several different spings. The more levers required to be operated: the lighter and more accurate the operation. Some systems used up to 5 or even more pivoting point and were therefore called a ‘5 stage trigger system’. Some even were so light that a few grams of pressure touch by the shooters finger actually fired the system. If this extreme sensitivity really made the pistol that more accurate.. one wonders!
