Went and compared Glock, Ruger, Springfield and Beretta. Unfortunately, they did not have a S&W M&P on hand. The Beretta just felt the most "right" in my hand, very natural. The Ruger was second in feel, but felt really heavy. The Springfield XDM was next, and that was sort of my lead horse going into this. So, I'm a proud new Beretta owner. Gotta re-up at the range so I can get myself dialed in.
