re: PX4 Storm vs. M&P

I was in the same exact situation about a year ago debating over the same two guns. I am a left handed shooter so I was looking for something ambidextrous. Though the PX4 and M&P both offer ambidextrous safeties and mag releases, only the M&P offers a slide releases on both sides of the gun as well. Because of this and the fact that I found the grip to be a little more comfortable decided to go with the full sized M&P 9mm.

A year later I never once regretted my decision. It's accurate, reliable and shoots great.
