Do you think that one day your kids, kids, will inherit your glock but the plastic will have become too brittle to shoot it? I love Glocks, and have owned several, but I am familiar with plastics and know that eventually they get brittle and break easily. I know I will be long gone, but I hope to leave my collection of firearms to my children, and then their children, so I just wonder what will become of the polymer guns. Please weigh in on your opinion.

I work with plastics, too, but I'm not a chemist nor a materials guy.  However, my guess would be that the fillers they use (glass, etc.) will give the plastic long-term retention of physical properties.  Generally, plastics won't spontaneously degrade - it usually needs some type of exposure to an external element to cause a breakdown - UV, ozone, chemicals, etc.

No, they will not degrade any more than any metal would.  Metal has to be kept away from certain things to not "degrade". same with plastic.

Stored properly, it would be good to go 200 years from now.

Cheep plastic will sit in landfills for thousands of years.....A Glock will out last that.
