From the FBI's website at www.fbi.gov. Violent Crimes staistics for 2011 Table 20 combined with 2011 Population estimates.

Your chances of being a murder victim are as follows:

Overall 1 in 24,500

Murder by Firearm 1 in 35,744
Murder by Handgun 1 in 49,323
Murder by Rifle 1 in 949,812
Murder by Shotgun 1 in 861,767
Murder by Non-Firearm 1 in 75,175

For whatever reason the state of Alabama is ommitted from the FBI stats, but these are the numbers based upon their data combined with 2011 population estimates from the census bureau.

It would seem that rifles and shotguns are the least of the problem, but you can do your own research if you are objective enough to bother.

Handguns are the most regulated firearms with virtually all being registered throughout the US.
