I'm not knocking why anyone needs a polymer 1911. I'm asking why?
I have a 1911 with an aluminum frame which when disassembled weighs almost nothing. I just don't get the trend toward polymer, at least in the handgun market. They do tend to be a little lighter but not by much and lighter isn't always better. Ask anyone who has fired a S&W .357 mag out of an Airlite J-Frame....it hurts!
Other than price, which is definately important, what is the infatuation with plastic? I just don't get it! Kimber tried, discontinued the model. Wilson is trying and we shall see, though they will be real pricey! You want plastic, ask Eric....BUY a GLOCK!
I nearly drank the kool-aid myself and sprung for an M&P and I may in the future, but for now....I like the feel and heft of a gun and the time and engineering involved in producing a precise instrument. Injection molding, while interesting, just doesn't have the same effect on my senses.
