What is the maximum range of a 40 cal handgun?

Answer 1

Maximum range the bullets will fly and still be dangerous? Probably 2 miles or about 3 kilometers. But if you mean the maximum range that you can expect to hit a man-sized target with just one or two shots, with the bullet still having enough velocity to do what you want it to do to that enemy, then that maximum distance would be about 50 yards or 50 meters.
