Stop Abusing your HP-22A's with high velocity ammo - the manual tell you to shoot only Standard Velocity ammunition.J22 is built like a tank compared to the HP22 peace of garbage. The guns been out for over 20 years and still cracks frames.... JUNK! Its also overley complicated to the point you would think an ex german hack engineer from H&K designed it.
If you want a really good reliable J22 just get yourself a J25. They are head and shoulders above the J22 in the reliability department and are not nearly as ammo sensative due to the vast superiority that is ... 25acp.....BOOOOOOOOOM.
They'll last years.
