Still cant bring myself to spend money on a plastic firearm. The MIMs process is about my limit. I have seen plenty of info on the plastic guns and it seems to be an ok material and will last a long time. This issue with S&W sounds like a qc error not materials. All that being said, I want to see a glock,smith,sig,fn,khar,etc after it has been around for 50-60 years of being in the sun and regular abuse. Plastic vs metal, my vote is metal.
Concur, they are throw away guns. In 20 years when no parts remain and the model is no longer manufactured try and get a gunsmith to make you plastic internal parts after its broke or worn. Don't waste your money, guns, gold and silver are and have always been the best investment you can make. Buy quality, not plastic/polymer.
In 20 years, if we are able to defend our rights and maintain a society, there will be no need for buying such parts. The 3D printers will be as common as your inkjet printer, and blocks of millable materials will be purchased at WalMart or online. You'll be able to make your own parts if they are not available, but in the long run, it will be a boon to parts suppliers. There won't be any need to maintain a huge stock of these plastic parts, simply an electronic file of specs from which to create new parts when ordered. And advances in materials will enable replacement parts to be better and more durable than OEM parts currently being used.
