Nothing at all wrong with a Polymer handgun. My Glock will outlast my grandchildren.
Some years ago I collected the WWII black polymer identification model airplanes. They were suspended by fish line in my office.
One day I noticed black droplets on my desk. One of the polymer airplanes was melting. I called the Smithsonian which has an extensive collection of these models and asked what I could do to stop the damage. They replied that after 60 years the polymer begins to break down and that the process could not be reversed or stopped. I can be slowed by keeping the models in a freezer.
Now when your polymer plastic guns begin to melt don’t be surprised. This is a worldwide conspiracy to rid the world of firearms.
