Since I live and police in a non CCW state I shouldn't opine about things I don't have knowledge of... But, when did that ever stop me.
Report the crime and your response to it. Lying even by omission will bite you in the bottom. Doesn't have to be a disposition just a sketch of facts in case it goes anyplace.... Lotsa stating of fear for my life and threats made and weapons displayed by offender would be in my report.
If you were right to use deadly force you were right to draw.
