On the bright side, the more folks who are buying guns, the more folks who are likely to vote for Pro-2A candidates, so these gun shortages most likely indicate a huge influx of new firearms owning citizens, and seeing as they bought them mostly for security, that means they aren't going to want to give them up, so at the very least, they won't be voting for candidates who are for Gun Control.
Also, most Glocks are double-stack "high capacity" firearms, so any attempts to push magazine capacity restrictions will most likely be dead on arrival.
