I recently traded a M&P45 straight up for a 4506, I purchased the M&P a few years ago to see what all the hoopla over plastic guns was about, while it was a reliable tool the trigger was very mushy even after smithing, accuracy was only fair. The 4506 has a superb trigger out of the box, is extremely accurate and every bit as reliable as the M&P. I'm very happy with my trade. To me the 4506 is a better pistol in every way except capacity 8 vs 10. I would pick a 3rd Gen over any plastic striker fired pistol.
