My best friend bought a Taurus for CCW, went to the range and it seemed to function ok. However, two weeks later on December 31 he was walking down the street when a criminal pulled a knife on him to rob him. He pulled out the revolver, only to have the revolver lock up on him. He got into a fight with the criminal, managed to disarm him, but in the struggle in the ground the criminal grabbed the revolver and hit my friend in the skull twice with it, cracking his skull. My friend had to have surgery to repair the damage.
I'd post the pictures here of him at the hospital, but am afraid they would be too graphic for this website.
