You have it backwards. Concealed carry does not guarantee low crimes rates as you have to contend with economics, people, culture, and the like. However, when you look at areas where gun ownership (not even concealed carry) is discouraged you have high or rising crime rates; Chicago, Washington DC, Detroit, Los Angeles, St. Louis, and New York City to name a few. No state does this but many cities do try to stop ownership of guns.

Countries such as Japan and England have virtual handgun bans and very low crime rates. Other countries have almost no gun control laws and also have very low crime rates. So it's hard to argue that more guns in the hands of private citizens leads to a lower crime rate.
However, in the second part -- I know New York City has instituted stricter gun control laws than many other U.S. cities. Can't speak for the others. And from every source I've been able to find, the crime rate in NYC is LOW. I remember reading that since NYC instituted these stricter laws, many guns used in crimes are being brought in from other states, West Virginia cited as the leader. For example:
