7  Defects of guns are divided into four groups:  common defects,  defects associated with internal ballistics,  functional defects of guns,  wear out of guns. 7

8  Common defects:  cartridge can not be loaded into the chamber,  weak function of firing,  strong function of firing,  weak shot. 8

9  Defects associated with internal ballistics are delayed gunshot and ignitor primer.  Delayed gunshot is caused by:  defective primer,  lack of strike firing,  impaired ignition powder charge,  lack of connection with cartridge bullet 9

10  Defects associated with internal ballistics are delayed gunshot and ignitor primer.  The shot, which is not normal to check the barrel after the shot.  This defect is very dangerous.  Another dangerous defect is a barrier in the barrel. 10

11  Functional defects of guns:  do not pass the cartridge to the chamber,  do not open the cartridge to the chamber,  do not pull out cartridge casing from the chamber,  do not throw out cartridge casing,  shooting emergency is not exposed. 11

12  Functional defects of guns:  premature shooting emergency,  weak strike to the strigger,  trigger doesn´t return,  magazine is released,  etc. 12

13  Each gun has got a certain life.  Life(time) of gun is defined in the specification.  Life(time) is determined by the number of shots.  Examination system quarantees safety and functionality of gun.  Defects are result of failure to comply with technical regulations or improper use of gun. 13

14  Gradual reduction in the functional properties of the bore :  a mechanical action,  a heat treatment,  an erosive action,  a chemical action. 14

15  Protection of the functional properties of of the bore :  construction of the barrel and the bore,  construction of cartridge and its material,  material of the barrel and the technology,  changes in the design of guns in use. 15
