Liipaisinta

Liipaisinta is a Finnish noun that translates to “the trigger” or “trigger mechanism” in firearms terminology. It refers to the component that, when pulled, initiates the sequence leading to firing. The liipaisinta engages the firearm’s firing mechanism by releasing the sear and allowing the hammer or striker to strike the cartridge primer, thereby initiating discharge.

In a firearm, the liipaisinta works in concert with other components such as the sear, hammer or striker, and often a disconnect or firing pin block. The design of the trigger influences the trigger pull weight and travel, which are important factors in handling, control, and accuracy. Common configurations include single-action triggers, where the hammer is cocked separately before pulling the trigger; double-action triggers, where pulling the trigger both cocks and releases the hammer; and striker-fired systems, where the trigger releases a striker rather than a hammer.

Some liipaisinta include safety features such as manual safeties, trigger safeties, or internal blocks to prevent discharge if not fully engaged. The feel and reliability of the trigger are major considerations in firearm ergonomics and performance.

Beyond firearms, the term can be used more generally to describe any control actuation that initiates an action, though its primary usage remains technical and domain-specific to firearms.

In Finnish safety and regulatory discussions, attention is often given to safe handling, storage, and training related to the use and management of triggers to minimize accidental discharge. See also: Firearm, Trigger mechanism, Sear, Hammer, Striker, Safety.
