This is just part of an article published in Guns & Amo Handguns. Just some info for those who like to bash so called "plastic handguns";
Everyone knew that real firearms were made from steel and walnut. They warned us that polymer handguns ("Tupperware pistols," as some liked to call them) would quickly wear out, degrade, melt or dissolve and scoffed at the notion that plastic could be as tough as steel. Despite these dire predictions and downright hatred directed toward them, polymer-frame pistols quickly became the hottest items on the police handgun market.
And for good reason. Modern polymers provide equal, if not superior, resistance to wear, abrasion, solvents, oils and environmental extremes as steel and alloy-frame pistols. The frames can be molded into a variety of ergonomic shapes that do not require separate grip panels, permitting them to use high-capacity magazines without increasing the bulk of the grip, making them adaptable to persons with smaller hands. They are lighter than steel or alloy, which is a big plus when you have to lug one around for eight or 10 hours a day, and they have the added advantage of flexing under recoil, absorbing some of the recoil pulse so they shoot softer than heavier handguns.
According to recent studies, it is estimated that more than 60 percent of American police officers now carry some sort of polymer-frame pistol. It didn't take civilian shooters long to recognize that the same features that made polymer pistols so practical for police service made them equally adaptable as home-defense, concealed carry, trail and competition handguns. Today almost every handgun maker of note offers a pistol with a polymer frame.
