Most people would be very disappointed if they heard real gun fire. M16's for example have a very tinny sound to it (it is a .22 caliber after all). The fact of the matter is that most people are used to Hollywood gun sounds. Even some hunters assume military weapons sound like they do in the movies. For the most part, they don't. Exception to the rule might be M2 .50 caliber machine gun. That one sounds like they do in the movies.
