First post. Bought a P380 today. Ran 100 rounds of Winchester white box through it with 5 stove pipes and 4 fail to feeds. The slide locked back after the final round on the first 2 mags. On the 3rd and all subsequent mags, the slide failed to stay open after the last round. This happened with both mags.
Prior to shooting, I cleaned and lubricated the gun well. I will run another 100-200 rounds through it (as Kahr says) before I let myself be disappointed. My wife's CW9 has been flawless right out of the box. Should I be worried or not?
