I'll link this story to where I read it (The Firearms Blog), but beware they are a linkfest site, with heavy advertising. It seems Mossberg bought up the old Chip McCormick patent for drop in triggers a while back, and has now decided to go after a bunch of small fry companies making such gadgets. I'm afraid things like this DO color my buying decisions. The firearms community is not particularly huge, with most companies we deal with being quite small. A relatively big company in the business that's attacking small entrepreneurs strictly for financial gain,. and limiting our buying choices by doing so..... that's a company I will avoid doing business with. It's not the first time Mossberg has pulled this stunt. I understand it as a business move, but understanding does not equal agreement. Just because the law says you CAN do something doesn't mean it's the RIGHT thing to do.
