342PD - is it scandium frame or not?

[dakota1911]

I thought S&W used Aluminum alloy doped with a small amount of Scandium in all their hand guns that use Aluminum frames. S&W has a patent for the process of how the Scandium is added to the Aluminum. At some point their marketing and sales people jumped on this.

This means that other people are using Scandium and not using the S&W process or paying S&W to use their process and not advertising it.

At one point I think they sort of overdid it with their 1911s.
