Shooting at a dog/yote or mountain lion with a handgun in a neighborhood is, shall we say, less than ideal. Most wont be hitting what they're aiming for. Most dont have the wherewithal to actually do the job properly cause it's very close in work. Most will be cleaning their shorts post incident as well.
You probably wont see the mountain lion attacking you either. If you do, its intentions probably arent an attack.
