One of the basic rules of modern gun fighting is to USE ENOUGH GUN.
The .380acp isn't a good choice as a main sidearm.
A few years back, an off duty cop in metro Las Vegas NV walked into a armed robbery with multiple subjects. He shot it out with a small caliber pistol & was seriously wounded in the exchange.
The brave officer was later named NRA law enforcement officer of the year.
He returned to full duty & started to carry his regular sidearm with 2 15rd magazines all the time.
