What I could find was that there are estimated to be about 350-500 million firearms in the US. The closest thing to a breakdown was 30-50 million semi-auto rifles, and probably close to a 60/40 split handgun to long gun over time (article shows trends). Murders per year using rifles and shotguns were less than 600 combined. Handguns accounted for over 6000.
So the number of hanguns is maybe something like 20% higher than long guns, but murders using handguns are 10x higher than with long guns.
