I just bought a M&P 9 mm shield a few weeks ago for my EDC. I have shot it a couple of times now and have been very happy with the performance. It definitely takes a little adjustment to get use to the very short barrel length. Going from your 4 inch barrel on your p99 to the 3.1 inch barrel on the shield will take some adjustment. Like I said, I love the gun and would buy it again, just a couple thoughts to keep in mind.
If you go with the Shield, look into Henry holsters, I haven't made up my mind yet but that's what Im leaning towards. Good luck with the decision
