SW.Ecks, I am glad to hear that you and your family are doing well and didn't get hurt in the altercation. You used your firearm in a defensive manner, which is the reason we carry them. Sounds like you are a very responsible gun owner. I say that because I probably would have fired until I saw spray. But you fired with the intent to hit, but only fired three rounds. The best part of this story is, 1) you had your pistol on you; 2) you deployed it after the threat was returning; and 3) you didn't have to "rack" the slide. Great job and blessing to you and your family.
Good job OP.
