There are approximately 271,000,000 people in the United States. It is estimated that 83% will be the victim of violent crime sometime in their lives. 271,000,000 times 83% is 224,930,000 people who will be the victim of a violent crime. It is estimated that 40-50% of the population owns guns. Thus 224,930,000 of these times 45% is approximately 101,218,500 of these victims who own guns. If the average person lives 67 years then by dividing 101,218,500 by 67 gives us an estimated number of yearly victims of violent criminal attack who owned a gun. This number is 1,510,724. Thus, I would estimate the defensive use of firearms at approximately 1.5 million every year. This is just a reasonable check (a common sense approach) on the stats being put out by various groups. In my opinion the study that only shows 80,000 defensive gun uses per year is grossly underestimated. This lends further support to Kleck's number of 1.2 to 2.5 million defensive uses per year.
