A single stage trigger releases the hammer without any discernable difference in trigger pull. A two stage trigger is one where after you pull the trigger back most of the way the pull becomes heavier just before the hammer is released. On bolt action rifles a single stage trigger is usually desirable. They can be extremely light, short and crisp. Bolt action hunting rifles frequently have pull weights of 2 lbs or less with almost no take up and target rifles often have trigger pulls that are measured in ounces. On a semi-auto rifle however a light, short single stage trigger like that just isn't safe. The recoil and the loading action would lead to accidental discharges. This is the reason most military style rifles have very poor triggers in comparison to bolt actions. Single action triggers on military type rifles typically have a pull about 1/3" long and maybe 6 pounds in weight. In order to combine a good quality trigger and a semi-auto action, two stage triggers are often used. To fire the rifle you still have to pull the trigger back 1/4" or so, which makes accidental discharge less likely, but then you feel that minuscule bit of resistance and know that only a slight pull is necessary to fire the rifle. You're most likely to find two stage triggers on military bolt action rifles, European rifles and high end semi-autos. |
