摘要:The article deals with possibilities of misuse of the non-lethal weapon system CZ 83 PA Rubber (product of CZ Uhersky Brod) for firing standard ball ammunition with metal projectile that is not intended for this type of weapon. The evaluated weapon system consists of modified semiautomatic pistol CZ 83 and non-lethal cartridges of calibre of 9 mm PA Rubber with a rubber spherical projectile. The results of theoretical analysis and also the results of practical firing tests that are unique from internal ballistic point of view are shown in the article.
