That just doesn't make much sense. To many variables and adrenaline to even think " it's time to press the mag release" while fighting for your life. In a CQ situation you would be better served using empty hand and/or knife tactics. With the current technology of retention holsters if he has your gun your probably not in good shape enough to hit the mag release. It's all debatable and my 2 cents.
"(Note: 1980-2014) In the last 10 years the average number of officers killed with their own gun was . . .
2.2 per year. According to the FBI UCR numbers, the average of all officers feloniously killed is 50. Gun grabs account for 4.4 percent of officers feloniously killed in the last 10 years with their own weapons. The number of sworn police officers in the United States in that period has averaged about 523 thousand a year. So the rate of police open carriers who are killed with their own guns is about .42 per 100,000. It’s not zero, but it is low.”
