I did a N.D. inside my car! Wanted to unload my gun & I was in a hurry. (Mistake 1) Racked the slide of my Glock 22, ejected a round, dropped the mag, and pulled the trigger. (Mistake 2! Should have dropped the mag then racked the slide - like I've done 10,000 times without incident.)
Two interesting things resulted.
1.The bullet, a Black Talon, shattered the radio. It kept on playing, like the car in that Stephen King movie, "Christine".
2. To this day, I don't remember hearing the report. But I'm sure it was loud.
