I have 2 PJK-9HPs,and a old Argentine, most barrel ramps have
pits in the ramp, dremel can make them smooth, or buy a barrel from Federal Arms Corp. I shoot mostly FMJ without a hitch, some
wide HPs will dig into ramp and a stopage, I believe te HP is easiest to field strip and shoot, try to remove the mag safety,
it will give a nicer trigger pull, alot of sites to learn on. good shooting!:ar15:
