![]() No matter what happens before or after, the motion of the trigger to move the sear off that hammer notch is commonly termed creep. A correct trigger has those angles such that the hammer must move ever so slightly farther to the rear to release. The sear is held into that notch which measures in the 10 of thousandths of an inch, by the sear spring with the engagement angles such that the sear tends to stay engaged. The sear engagement in a simple hammer and sear trigger system is a narrow notch usually on the hammer. Some trigger designs have more travel than others and can't safely be tuned up to reduce the travel distance.the key is not so much the amount of travel but rmostly to have it smooth and even throughout that stage. I would call a hair trigger one that has both a very light pull weight and also very little travel. The term hair trigger is like the term creep.Not a textbook definition, but pretty common when some folks talk guns. Usually it will be called creep on a "bad" trigger, one that is rough or has a lot of travel. Apply nice even pressure up to the point of that nice crisp snap. It's also many times likened to feeling a glass rod break. The point after the initial take-up is gone, you've got tension on the trigger, and the trigger actually starts moving itself to disengage itself from the sear.Ī well tuned trigger should have a nice smooth "travel" that has a fairly even pull weight and no rough or gritty feel to it. Going by what Alpo posted (the "proper" terminology).Ĭreep would be what he defined as the travel portion of the trigger movement. It was so light, that weight of a hair landing on it would set it off. I've always heard that a "hair trigger" was one that had an extremely light pull. There are things called "trigger stops", that prevent overtravel. Continuing to move can cause you to pull the gun off target. You want the trigger to break (that's what it's called when the hammer releases - the trigger "breaks") and then stop. Preferably, you don't want any overtravel. ![]() That's the distance the trigger moves after the shot has been fired. That's the distance the trigger moves, from when you first have tension on it until the hammer falls. You can work with it, but the better triggers don't have any. Double action automatics, when the hammer is cocked, usually have a lot of takeup. Military rifles often have a lot of takeup. That's called "takeup", and sometimes "slop".
