Anyone have any idea how I could replace the trigger spring on a Kimar model 92 8mm? In order to fire it I have to push the trigger forward before pulling again, the spring broke a while ago and I have no idea how to fully disassemble a beretta (I only know 1911's) and this isn't even remotely close to any beretta when it comes to internals...I just know how to field strip it. Any suggestions?
