Actually two of the companies are foreign owned (SIG and Glock), so I rather expect they just want to steer clear of the politics. That is, of course, rather a myopic view, but I can see the local corporate officers making the case only to have the home officers in Austria/Germany saying no.
Now as for Ruger and S&W, they don’t have much excuse. Ruger has always been quite self serving when it comes to gun laws though. They were in favor of the 94 AWB because it exempted the Mini 14.
the person who was responsible for that fiasco has passed away and no longer with the company.
The new managment does not seek to make the same mistake.
The prior managment tried to discriminate against people who rode motorcycles to work and that was a financially painful decision in the 1990s.
keep in mind 3d prinding now makes their magazine market hold dubious. In addition, you have home railgun and coilgun projects which are bypassing even the need for gunpowder.
See post 22. Bill Ruger is dead and the current management is now making the “high capacity” pistols, “evil black military” rifles, and all the other things Ruger would not countenance while he was alive. They also are a lot more pro-2A than ol’ Bill was.
