The problem of production accuracy and precision, as well as the shape and position of movable and immovable integral parts of assemblies and mechanisms is the topic of many papers. Similar problems are met at the hand arms design. One of the main characteristics of hand arms is certainly the accuracy. Accuracy of shooting depends on various factors: the position of barrel muzzle during firing, shapes and types of bullets, but especially, trigger mechanism displacements and forces balancing. The relation between the trigger mechanism and the shooter is content in fact that forefinger force acts on the trigger, during the process of triggering, changing the position of the barrel muzzle according to the triggering mechanisms internal forces and momentums. This article describes a negative effect of size tolerance on the trigger characteristic. The trigger characteristic is the dependence of trigger force and trigger angle. An invalid trigger characteristic affects the accuracy of shooting and can be changed by not only proper choice of dimensions, but also the location of individual components. The paper shows an example of trigger mechanism that is designed as a Glock type mechanism. The solution for designers of small arms authors suggested the use of software MW.
