Although there is no evidence to indicate gun ownership deters overall burglary rates, gun ownership may be a factor in deterring burglars from entering occupied dwellings ("hot" burglaries).

In studies involving interviews of felons, one of the reasons the majority of burglars try to avoid occupied homes is the chance of getting shot. (Increasing the odds of arrest is another.) A study of Pennsylvania burglary inmates reported that many burglars refrain from late-night burglaries because it's hard to tell if anyone is home, several explaining "That's the way to get shot." (Rengert G. and Wasilchick J., Suburban Burglary: A Time and a Place for Everything, 1985, Springfield, IL: Charles Thomas.)

By comparing criminal victimization surveys from Britain and the Netherlands (countries having low levels of gun ownership) with the U.S., Florida State University criminologist Gary Kleck determined that if the U.S. were to have similar rates of "hot" burglaries as these other nations, there would be more than 450,000 additional burglaries per year where the victim was threatened or assaulted. (Britain and the Netherlands have a "hot" burglary rate near 45% versus just under 13% for the U.S., and in the U.S. a victim is threatened or attacked 30% of the time during a "hot" burglary.)

John Lott and David Mustard, in connection with the University of Chicago Law School, examining crime statistics from 1977 to 1992 for all U.S. counties, concluded that the thirty-one states allowing their residents to carry concealed, had significant reductions in violent crime. Lott writes, "Our most conservative estimates show that by adopting shall-issue laws, states reduced murders by 8.5%, rapes by 5%, aggravated assaults by 7% and robbery by 3%. If those states that did not permit concealed handguns in 1992 had permitted them back then, citizens might have been spared approximately 1,570 murders, 4,177 rapes, 60,000 aggravated assaults and 12,000 robberies. To put it even more simply criminals, we found, respond rationally to deterrence threats... While support for strict gun-control laws usually has been strongest in large cities, where crime rates are highest, that's precisely where right-to-carry laws have produced the largest drops in violent crimes."
