I'm still trying to figure out what the OP intended this thread to be about... Is this simply a thread in which to bash all the popular, big-name brand guns that we have decided we don't like? Or a brand we have decided we hate because we picked up one bad example?
If so, I'll throw Ruger and HK under the bus; I like pretty much everything else (including Colt, Kimber and Taurus, so there). But I still own Rugers and HKs.
Otherwise, who really cares? Because every major manufacturer puts out some lemons, either specific models, or production runs. And every company has gone through cycles in which their customer service has not performed up to the level we'd wanted...
Guns, like every other consumer product, are viewed through intensely subjective prisms by both their supporters and their detractors (haters, for you young'uns).
I've had disappointments from every single firearms manufacturer out there (well, except for Hi-Point, 'cause I never bought one). I'm over it. Doesn't stop me from buy from any particular brand again.
