Having worked for SW (SWSS, duh) AND i own a M&P40 and a SD40VE AND a Glock or 2...The M&P line is a great line of weapons, I bought my dad a M&P22 (same fit and feel) but the SD is a value gun, a real daily side piece, what it was designed to be. Why does it really matter? Because lets be realistic, in the 8-16 ft I hit you with a 40cal what I paid for my pewpew is kinda irrelative. Kinda like bewbees, some like'm big and well the rest are :supergay:, I guess...
