If you are not being threatened with violence then pointing a
gun at the other
person would constitute assault with a deadly weapon (felony) and brandishing a firearm. If you didn'
t have a concealed carry permit, you would also be guilty of carrying without a permit (first offense misdemeanor or felony, second offense felony). You would be arrested, lose your
gun, go to jail, probably for more than a year, and lose your
right to keep and bear arms. Exact penalty would depend on plea bargaining, the quality of your attorney and what the judge had for breakfast.
