Hey everyone, newbie here. I just bought a PPK/S for my wife, we took it to the range and it stove piped 35/40 rounds. Very frustrating. We were using Fiocchi FMJ. We did shoot one round of Winchester hollow point and it stove piped too. The gun shop had me leave it with their gunsmith, but I'm not sure he'll know what to do. I've read about trying different ammo, changing to a lighter spring, running 150 rounds through... I've never owned a firearm before that functioned this poorly. My wife's in love with the gun and I'd love to love it since it's so beautiful, feels and shoots great (one at a time). The guy will refund my money, and I could try buying a different one if this is just a lemon. Advice? Thanks in advance!
