If you have tried assorted ammo and eliminated that, You might try another mag to see if he same thing happens. I have had several of the .380s over the years. All were used. Never had a feed issue with any of them. I would doubt that there is a feed ramp problem if it feeds all the other rounds.
I would suggest tinkering with the feed lips on the magazine, but not on a new gun. It could affect your warranty.
