摘要
枪弹痕迹形成于枪支装弹、击发和退壳过程中,能够不同程度地反映枪种特征.本文利用显微镜对格洛克 19 型手枪发射六种国际现役的 9 mm北约标准弹(CBC-9mm-15、FC LUGER 9MM、GCED LUGER 9mm、WIN LUGER 9MM、CLA 9MM 16、S&B 11 9×19)的射击弹壳痕迹进行观测、分析.结果表明,不同弹种的同类射击弹壳痕迹特征均具有较好的稳定性和较高的出现率,且实验中射击弹壳的击针头痕迹、击针头孔痕迹、舌痕、抛壳挺痕迹、拉壳钩痕迹、弹壳口扇形刮擦痕迹的形态反映、留痕部位及出现率均反映出该格洛克19型手枪射击痕迹的稳定特征,可为司法实践中枪种鉴别与枪支认定工作提供一定参考.
Abstract
The formation of bullet cartridge marks,stemming from the processes of loading,firing,and ejection,serves as a varied indicator of specific gun characteristics.This study employs microscopic analysis to meticulously observe and interpret the shell casing marks left by six internationally utilized 9 mm NATO standard bullets(CBC-9mm-15,FC LUGER 9MM,GCED LUGER 9mm,WIN LUGER 9MM,CLA 9MM 16,S&B 11 9×19)fired from a Glock-19 pistol.The findings reveal a remarkable consistency and prevalence in the characteristics exhibited by comparable shell casing marks across various ammunition types.Specifically,the morphological details,location,and frequency of marks including firing pin marks,firing-pin hole marks,tongue-like marks,ejector marks,extractor marks,and the fan-shaped scraping marks at the mouth of the cartridges,all underscore the distinctive and stable signature of the Glock-19 pistol in its firing mechanism.Consequently,this research offers valuable insights and serves as a reference tool for forensic firearms identification and gun traceability in judicial contexts.
