Video: Miculek Pistol Comparison
Miculek compares the size, weight, ergonomics, operating mechanisms and trigger pulls of three popular polymer pistols.  He doesn't hide the fact that he is a S&W representative and, predictably, decides the M&P9 is his choice but the information he presents is pretty objective.

A fun video if only for his Louisiana accent and his repeated references to a "captivated recoil spring". BigGrin
