I've recently purchased a Sig P6 9mm in very good condition. The P6 was a German military sidearm, and as such was made to use ball ammo only. Other than occasionally misfeeding the conical shaped Hornady Critical Defense FTX ammo, it works perfect. Does anyone have any suggestions for hp self defense ammo that are shaped more like regular ball ammo? Maybe a round nose hp with a rubber or plastic nose? Thanks in advance.
