What is so dangerous about the FN semi-automatic handguns? Sounds like many other 9mm and .40 handguns made by other manufacturers to me.
I suppose dangerous means they will explode if you touch them.
They also have a built-in electronic chip which only allows them to shoot at cops. That is why they are called “cop killer” guns.
FN makes a Five-Seven which shoots a very high velocity .22 (actually a 5.7mm) cal bullet that some say can penetrate lighter body armor. I don’t believe there is any evidence that it is deadlier than 9mm or .40 cal but like the federal “black talon” bullets it has developed a reputation based more on urban legend than reality. It is still nowhere near as lethal as a 7.62 x 39 bullet from the AK-47’s that are ubiquitous throughout South America.
