Here's a better question: how are we supposed to believe that American wizards didn't create magic guns?

>a person with a gun could take even the most powerful wizard.
Correct, which is why Wizards stay hidden in the first place. A SWAT team could easily take on anyone at Hogwarts, but send them into the school and they'd likely end up in their homes with with no memory of the event and wondering what the hell happened last night.
>if voldemort won in the end and went on to wage war against muggles he would have died in less than 24 hours
Also doubtful. The Ministry had the UK Prime Minister in its pocket, so it's reasonable to assume that wizards were in control of other world powers as well. It wouldn't be a war, it'd be a slow assimilation leading up to a reveal once the muggle population had been properly groomed and prepared, like an alien invasion.
Of course, that's assuming that anyone in the Wizarding World has a brain, which they don't.
