Mainspring (firearms)

ID: mainspring-firearms

In firearms, the term "mainspring" refers to a key component of a firing mechanism, particularly in older firearms and some modern designs. The mainspring is a coil spring responsible for providing the necessary force to operate the action of the firearm. Its primary function is to drive the hammer or striker forward when the trigger is pulled, ultimately striking the firing pin or directly igniting the cartridge's primer.
