Experimental Investigations of Motion of Slide of Selected Pistol Types

In the presented paper, kinematic characteristics of movable parts of investigated pistols have been experimentally determined with application of high speed camera and appropriate software TEMA motion. Results of measurements can be useful in validation of various theoretical models and can reveal the influence of some technical solutions on parameters of motion of selected parts. Obtained curves presenting dependence of slide velocity versus time, allowed for rough estimation of average value of interaction force between slide and frame of the investigated construction. The results of study highlights advantage of HK USP pistol design. The achieved results are from reduction of the value of the mentioned interaction force (approximately 50%) due to elongation of the most intensive phase of slide motion damping process.
