1871年,德国毛瑟兄弟研制出第一支金属外壳子弹的步枪。一改过去枪支从枪筒装填火药的繁琐程序。1894年,毛瑟兵工厂的技师费德勒兄弟又研制出击发式自动手枪,取名“毛瑟手枪”。这种手枪虽然进入了击发式,使用便捷,但有一缺点,那就是射击时弹跳出的弹壳总是在射手面前跳动,既有击伤射手面部的可能,又分散射手的视线注意力,让许多射手不喜欢毛瑟手枪。 In 1871, the German Mauser brothers developed the first rifle with metal shell bullets. Alter the cumbersome procedures of gunning gunpowder from past guns. In 1894, the mechanic of the Mauser Arsenal, Federer Brothers, developed a hair-firing automatic pistol named “Mauser pistol.” Although this type of pistol into the firing type, easy to use, but there is a flaw, that is shot shells bounced out always beating in front of the shooter, both the face of the shooter may damage the face, but also scatter the attention of the shooter, so many Sagittarius do not like Mauser pistols.
