摘　　要：由制式64式手枪改制的枪支,其射击弹头、弹壳上的痕迹位置、形态也因改制手法和部件的不同而存在差异,给检验增加了难度,利用其射击弹头、弹壳上的痕迹对发射枪支进行同一认定具有重要的意义。本案中,笔者在非制式64式手枪的拉壳钩上使用颜色标记,并对标记枪支发射的带有自制底火的改制弹壳进行检验,从而对拉壳钩在异常位置遗留的痕迹进行了确认,为使用异常位置拉壳钩痕迹进行发射枪支的同一认定提供了依据。The pistol of type 64 has been fading out of people＇s sight.Yet its modified versions are still found in civil society.Because of the modifications with various means and techniques as well as the dissimilar parts,there are differences from the normal counterparts at both the patterns and positions of marks left by the shot bullet-heads and cartridge,bringing difficulties to investigators.However,these marks can play their effect in identifying the relative guns involved in cases.Here,we describe such a case.Through marking a shell hook with color and testing the shell with homemade primer which was fired by the examined non-systematical type 64 pistol,we confirmed that the examined shell was indeed shot by the examined nonsystematical type 64 pistol,providing an example to identify the fired gun with the abnormal mark left on shell hook.
