Presented for your information. Haven't read it in detail and make no claims about it. Seems to indicate positive but small benefits and even if small - doesn't support blood in the streets. Here's the conclusion:

IV. Conclusion
It is a common belief among persons advocating
for Second Amendment rights that allowing pri-vate citizens to carry concealed guns would deter crime. Most of the prior research on this topic deals with concealed carry laws and not the actual number of concealed carry permits. The only prior study that attempted to examine the effects of the
number of concealed carry permits on crime rates
was Lott (2000). The present study differs from
Lott (2000) in that it uses actual and much more
recent data. Although relying on actual data
reduces the size of the sample, the use of actualdata should increase the robustness of the presentstudy.
Results of this study suggest that four crimes were significantly and negatively affected by the per capita number of permits: violent crime, rape, aggravated assault, and auto theft. Hence, the greater the number of concealed carry permits, the lower are certain crime rates. These results lend support to Lott’s findings in More Guns, Less Crime. It is important to note, however, that the magnitudes of these effects are rather small, with large percentage increases in concealed carry permits required to produce even minimal declines in the affected crime rates. Even though the results of this study suggest that an increase in concealed carry permits may result in a reduction in certain crime rates, public policy decisions should not be based solely on these findings for two reasons. First, it is important to note that not all concealed carry permit holders are always armed in public. Hence, data on the number of concealed carry permits may overestimate the actual number of armed citizens in public areas at any given time. Second, results of the present study are based upon data from only four states over a 12-year period. Although this constraint was necessary due to the lack of available data, the results of the present study may not be applicable to other states or time periods. More comprehensive data on the number of active concealed carry permits is needed for researchers to more accurately assess the impact of increased firearm availability on crime rates
