DrJason, That's a tough one because though similar they are different. Size wise I prefer the slightly longer grip on the Beretta. Accuracy wise again the nod goes to the Beretta, it has a better trigger. That said I really like the M&P9c and carry it often. I think S&W in their effort to regain a share of the LE market hit a home run with the M&P series. Now between a Glock and the M&P I feel the Smith is a better gun. Comparing it to the Beretta is tougher and don't think you could go wrong with either. You could do like I did and buy both, that really works. I do like the simplicity of the M&P but I really like the traditional da/sa of the Beretta and feel it's a safer pistol. Bottom line though I have to say I like them both equally.
Monday I'm sending the PX4 Compact to Robar for their NP3 finish, while it's gone I'll be carrying my trusty M&P9c.
