Perhaps I missed it here, but a fairly recent study in Applied Economics Letters reaffirms a previous study in 1997:
It is an overreach to create a cause-effect relationship between gun laws and crime rates but the study is another datum to refute the rhetoric of the gun grabbers.

He is careful to note that additional research is needed (that's almost a given, right?).It may make sense to assume that states in which there are tight laws on weapons would make that state a safer place and one with less gun crime, however, recent research argues that the very opposite is true.
Mark Gius from Quinnipac University, published in Applied Economics Letters, suggests that this is in fact not the case, research shows that in states with more restrictive concealed carry weapons (CCW) laws there is actually an increase in gun related crime.
