I bet this is one of the more divisive designs. Some people will see this and go out and buy it immediately, others will see it and go on a Twitter rant about gun control. Both sides may have a point. There are some states where this would be an absolute hit, and others where you'd get shot in the back by a police officer. That all depends on the open-carry gun laws.
In terms of design, I like that it has a built in handle-grip. You know how they make those cell phone cases that are also wallets? They should make cell phone cases that are also guns. "Can I put you on hold? I need to make sure the safety is on. (beat) It wasn't. Phew. Glad I checked. Oops. Can you hold again. There's an active shooter here and I'm going to stop him."
