Abstract: This article describes a negative effect of the size tolerances on the trigger characteristic. Trigger characteristic is a dependence of the trigger force on the trigger angle. The faulty shape of the trigger characteristic affects shooting accuracy and its can be changed not only by the right choice of dimension, but also by location of the individual components. The article shows an example of the trigger mechanism which was designed as Glock type mechanism. A  solution for small arms designer is suggested using author’s software MW.
