I just bought a New Walther / S&W PK-380 Today and went to the range sent 100 rounds down range, ammo not going up the ramp correctly and jamming, ammo primer getting hit with the firing pin way off center and not firing, spent rounds not ejecting then it would fire correctly a few times then jam again. I don't think the slide is supposed be in the open position with no mag, is it? What do I do about all the other problems. OMG I feel so ripped off by S&W. PLEASE SOME ADVICE??, I must use this firearm in the performance of my duties.
