Need some opinions from those who have owned or tried both. I have shot the M&P9 multiple times and have fallen in love with the pistol. The ergonomics make it feel like it was made for my hands! That being said, finances are a bit right around here right now but I REALLY want to nab my first handgun soon. That brings me to the shield. It's a single-stack M&P, correct? How does the grip feel compared to a full size? Does the felt recoil increase/decrease? The shield is a bit cheaper than the full sized pistols so I'm tempted to go that route to save some change as long as the pistol retains its incredible ergonomics. Thoughts?
