Actually, the vast majority of handguns that are used to kill someone in the U.S. are STOLEN--not purchased. And, I think this would be a safe bet in most parts of the world. Most people that purchase handguns in the U.S. are law abiding and do so for two reasons, self/home protection, and sporting purposes. CRIMINALS DON'T BUY GUNS--THEY STEAL THEM. And, if you have been convicted of a felony in this nation, by law you cannot purchase any form of firearm.

In many instances, where handguns are used competitively, the guns are either transported to the range in locked cases that are placed in the car's trunk, and the ammunition is in a separate, locked case. In most states, this is required by law. The only folks that ignore that law are usually criminals who stole the guns to begin with. At some of the larger ranges, they have special lockers just for the purpose of storing the gun at the range.
