I had heard the guy who owned it decided to make some different kind of gun(s). Is he doing so? The Wikipedia article on USFA says the company hasn't existed since 2011. Has the owner started a new entity to manufacture his new guns, or has the whole project just evaporated?

It's dead.

Don't know for certain, but suspect they went too wide with their offerings, which gets expensive. Too bad, they are apparently wonderful guns, and go for big bucks now.

I kick myself in the azz for selling my 7 1/2" 44 Spl/Russian Flattop Target. It had an optioned set of XXX English walnut grips that were to die for and all of it was fit to perfection.

I never quite figured out why they shut down when they sold every revolver they could make??Super high quality guns.
