We are in a topsy-turvy mixed up world right now ("Thanks for that observation, Captain Obvious!").
I've seen both good and bad come out of a foreign owned entity purchasing a US firearms company. It's better to have competent knowledgeable management albeit foreign than for a disinterested consortium of US investors taking over. That's what got Colt, Smith&Wesson and Remington into trouble (well, Remington had other issues, too). Colt has really come a long, long way since CZ took over, in my opinion.
Ruger: Well, as Anchorite pointed out (we "seniors" have a long memory on some of these things), Bill Ruger wasn't a bright shining star when it came to our 2A rights. And, yes, the foreign ownership is troubling from that aspect also. However, right now Ruger has its issues too, and they need a steady hand on the rudder. That's been lacking in recent times, in my opinion. I guess we'll have to wait and see if Beretta does a takeover or not to find out if it's going to be to the betterment or to the worsening of Ruger. But, please, Beretta, don't mess up the production of the Marlins! Please!
