Would stricter gun regulations decrease the number of violence crimes committed in the USA?

I believe that stricter gun regulations would certainly decrease the number of gun crimes in America drastically - but that is not to say it would decrease the number of violent crimes. As the law stands, virtually any citizen has the right to carry a gun on them. This means in the heat of the moment, it is surely too easy to grab for the lethal weapon which can seriously injure if not kill an individual. However, if gun laws were regulated in the first place, then more often than not, in the heat of the moment an individual would not have a gun to turn to. But just because there is no gun to turn to, this surely doesn't mean that a violent crime would not take place - just a different sort of crime, and perhaps less lethal! Stricter gun laws are certainly the way to go for America to increase the disgraceful number of gun crimes in the county, but it's not necessarily going to reduce the number of violent crimes on the whole - as something, physical fighting or other weapons such as knives - might replace the lethal gun.
