It also has a reputation of being one of the most reliable, simplistic and easy to use/maintain guns used by military and law enforcement around the world. So much so that other highly reliable Striker Fire handguns all basically cloned the Glock design (Smith & Wesson's M&P line, among others). I'd bet there's influence coming from both ends - those who used them in video games and decided their first gun just couldn't possibly be a Glock, and those who see Special Operations guys using them and decided their first gun just had to be a Glock.
