You need lots of crime for that, we dnt have enough. Only 1.5 million violent crimes each year. A minority of the population can't be stopping 2 million moron.
We have 1.5 million successfully committed crimes, but for every c rime committed there are many multiples of crimes that were averted for various reasons.
Do you actually know anyone that made a living from robbery or break ins? I have known plenty of them, and for every crime they pull off they have half a dozen that they abandon for bad vibes, the owner came home suddenly, they got cold feet for some reason, etc.
So that would give about 9 million crimes averted each year. Could a big slice of that be due to the perp seeing his target is armed? of course. But how many? I don't know.

"The Institute of Medicine and the National Research Council released the results of their research through the CDC last month. Researchers compiled data from previous studies in order to guide future research on gun violence, noting that “almost all national survey estimates indicate that defensive gun uses by victims are at least as common as offensive uses by criminals, with estimates of annual uses ranging from about 500,000 to more than 3 million per year.”
CDC Study: Use of Firearms For Self-Defense is ‘Important Crime Deterrent’
"Though he stresses that the results of the survey are preliminary and subject to future revision, Kleck is satisfied that the survey's results confirm his analysis of previous surveys which show that American civilians commonly use their privately-owned firearms to defend themselves against criminal attacks, and that such defensive uses significantly outnumber the criminal uses of firearms in America. The new survey, conducted by random telephone sampling of 4,978 households in all the states except Alaska and Hawaii, yield results indicating that American civilians use their firearms as often as 2.5 million times every year defending against a confrontation with a criminal, and that handguns alone account for up to 1.9 million defenses per year.
