I don’t think it’s the fact that they’re armed that makes them not feel safe. It’s the constant fear propaganda they’re fed via Fox News, Facebook, Twitter, and other right wing “news” sources. The alt right propaganda machines scare these people into thinking that everyone and everything is out to get them so they go out and buy a gun. In more civilized progressive areas, people aren’t exposed to alt right fear mongering as much and if they are, their community disproves and supports them so they don’t fall down the “I must arm myself to kill anyone who might harm me” rabbit hole.
It’s the HK G11 and FN P90. Both guns have a magazine where the cartridges aren’t in line with the chamber so each cartridge needs to be rotated before it can chambered. HK decided to commune with ancient clockwork gods to learn the secrets of kraut space magic while FN just went with a curved ramp.
