I will later but if you want to look it up for yourself I will give you the places to look. There are numerous different pages and it would be a pain to post them all.
http://www.fbi.gov/about-us/cjis/ucr/ucr -- Here you can search through the UCRs of years past. UCR stands for Uniform Crime Report, and most agencies contribute to this information.
Useful information at these as well:

http://www.icpsr.umich.edu/icpsrweb/NACJD/NCVS/
http://www.icpsr.umich.edu/icpsrweb/NACJD/NIBRS/
http://www.nraila.org/Issues/FactSheets/Read.aspx?ID=128
These should get you started. It will take you awhile to get through it all, but this is where the information can be found. There are also reports conducted by numerous different organizations and the individuals. Go to
www.nra.org and search for crime statistics and the like.
Here is a link to 18 USC 922 where the FGFSZ is located:

I would also reccomend you read the book "More Guns, Less Crime" by economist John Lott. This is where I have studied this information in detail, and he goes above and beyond in his research, and breaks everything down into individual counties in each state (where data is available). It is hard to argue against his research, as it is the most extensive there has been to date.
http://www.cato.org/event.php?eventid=7235 -- debate between John Lott and previous Brady president.
You can get the book at
www.amazon.com for a kindle for only $5. If you don't have a kindle, you can download a free version of kindle from Amazon for free, and the book will be on your computer in seconds.
Here is an interesting article:
http://www.cato.org/publications/policy-analysis/fighting-back-crime-selfdefense-right-carry-handgun
It is lengthy and it is from 1997, but it still shows the correlation between more guns and lower crime.
