Well, Welcome to the FTF Community.
Might suggest you stop by the introduction section and let the guys know who and what you are about.
With one time of ammo, and presumably only one magazine tried, that is not easy to diagnose over the Interwebz.
First, I would check the feed ramp with a cotton ball. Does it snag or hang when you rub the cotton ball across the feed ramp?
Second, I would recommend trying some different ammo and perhaps an additional magazine or three to see if the problem persists...
I wouldn't accept that from a brand new pistol though. If you can't get it to work, ship it back and get something else.
