Hi, My dad bought a new hi power, slide kept seizing up with round in chamber, couldnt move it back or forward, kept pressuring the slide back and forth, eventually got it cleared and empty. sent pistol back, they repaired it, wouldnt say what was wrong, even after calling. Just got it back, doing the same thing. anyone know what might be the problem, or likely suspect issues? Thanks for any information Wanna kill these ads? We can help!
