Arcadia Machine & Tool?
Here's the deal. They were an above average machining shop that got the idea to make some handguns. They are most famous for the Automag series of pistols that were made famous by Mack Bolan books and Sudden Impact with Dirty Harry.
They made waves, but they had some serious reliability issues. If you got a good one, it worked and worked well. The problem was, there wasn't many "good" ones that got out into the market.
They were named in a shi*ite load of lawsuits, so they filed for Chapter 11, then they re-bought the company with the protection of an incorporation.
Today, some of their weapons are produced by Hi Standard, a company that has changed hands a couple of times.
Personally, no matter how good the weapon feels in the hand, I would stay far away from it unless you are making a movie and can afford to add CGI.
