My Colt Gov't 1911 ia 92 years old and my Colt Combat Commander is 35 years old and they both run like watches.......my question is, what could someone expect the longevity to be on the new polymer guns. I believe over a period of time plastics / polymers break down due to factors such as continued use of solvents, UV rays, chemicals found in powder residues, cracking, etc. Could someone expect to see the years of longevity from these new pistols like we have witnessed from the steel frames of yesteryear.........?
