IMO Glock hasnt really done any overhaul since it they hit our shores...a few cosmetic changes like finger grooves and a rail (oooooo ahhhhh) but overall the same. Like others have said, if it aint broke, dont fix it....and I agree to some part however, i dont think the home office in Austria realizes just how fickle the gun buying public is here in the states...a lot of people always want the newest, latest and greatest...even if it isnt any "better" its still the new thing.. Why do you think all the big guys come out with a new "miracle" cartridge every 3 years??? It isnt because the old ones stopped working....its to make sales ..period. With that being siad, I think a :new" Glock would sell like hotcakes, even if it isnt any "better" it would just be the New Glock...course then the Old ones would crash in value and be stacked up like plastic cordwood and we cant have that! LOL Just my 2 cents
