الملخص

A study on the combine effect of mechanical adhesion, erosion and cavitation erosion of the pistol barrel and determining its resistance to the combined effect of these processes. It points out the effect of wear or any kind of corrosion features on the accuracy of weapon. The results showed the importance of using recent instruments in analysis and the importance of analyzing the measuring of pistol barrel and bullets to sustain the relation between them, and the importance of finding the gun used in a crime immediately after its happening.
