摘　　要：因枪支机件陈旧松散、保险机件失灵导致枪支在拆卸、擦拭、触摸、磕碰等过程中引起走火是较为常见的枪支走火原因。本文介绍了一起因变造射钉枪裸露击发扳机受到包裹物撞击引起走火而致人死亡的案件,结合现场勘查及尸体检验的意见,对死者枪创的形成方式及变造射钉枪能否走火等问题进行了模拟实验。通过实验的方法还原了枪支走火的全过程,分析讨论了变造射钉枪走火的规律、特点,能为类似案件侦办提供参考。At present,most cases of guns misfi re are caused by the old and loose gun parts and the failure of safety parts,which leads to guns misfi re in the process of disassembly,wiping,touching and bumping.This paper introduces a case in which the naked firing trigger of the altered nail gun was hit by wrappage,causing death.Combining with the opinions of on-site investigation and autopsy,a simulation experiment was carried out to explore the formation mode of the shooting wound of the deceased and whether the gun misfi re could be caused by hit.The whole process of gun misfi re was restored by experiment,and the rules and characteristics of gun misfi re were analyzed and discussed,which could provide reference for similar cases.
