Assuming the weapon is in good repair and has a clean bore and clean, unobstructed gas tube, there should be NO problem feeding hollowpoints from any of the good quality ammo manufacturers. Out of eleven years as a Peace Officer, I've carried a P7M13 for the majority of those years as my duty weapon. I own four P7x-series weapons and I generally carry CorBon DPX 9mm 115gr +P rounds. I've carried CorBon since before they partnered with the DPX product too. Never a lick of trouble."Thank you" to everyone who has responded to the question.
Here is a little background. I was asking on behalf of a friend who wants to carry a P7 he has as an undercover gun. He asked me because he has indeed tried several brands of holopoint ammo and had some malfunctions with it. I told him that I would post the question on this board to find out more info for him.
I will forward on the reccomendations suggested here.
