Valox and Zytel are manufacturers names. There are many suppliers of plastics these days, so not using a brand name doesn't mean as much anymore. To jump from my non-use of those trade names to us using recycled or inferior grade of Nylon is not a good conclusion. We use a Glass filled Nylon that has properties equal to those trade names. Typically it is a nylon 66, but not always depending on what we need from the application. We would not degrade our plastics by using a % of plastic regrinds in the formula (this severely impacts strength, as we learned the hard way long ago.). Anytime we need to look at different supplier or type of plastic, we do a rigorous testing loop to ensure we are not losing anything by the switch.
Bantam handles are still made overseas, with locally sourced Nylon
I don't remember any 442 handles (or parts for that matter, maybe rivets) made from overseas parts. But that was awhile ago, so I don't remember off the top of my head). The plastic listed on the print Is Polypropylene
