Ideas... The grease nay be an isse.
I think I would phone the manufacturer before doing any polishing because it is new. I would not want to risk giving then an excuse not to fix you up.
I would try a few hundred rounds first. Remove the grease in case that is slowing down the slide. Bring some oil to the range. You can try oiling the nose of the first bullet in each magazine you shoot, not likely to help, bit no harm to trying in case you are hanging up on the feed ramp. You can try oiling the slide, NO grease for testing.
Check to see if the feed ramp is smooth. I bought an inexpensive used auto pistol that would not cycle properly, I cleaned off the grease, polished the rails and the feed ramp with fine sandpaper, then it worked perfectly after that.
I prefer revolves to pistols but revolvers fail also.
I had to pump a box or 2 of ammo through an A5 before it worked perfectly. Never missed a beat for 3 decades or so, break in may be needed to mate the friction points.
Best wishes with your new pistol. I am confident the problems will be resolved.
