Reply #1: Two ways to look at it

[SlipperySlope]

There are two ways to look at it.

First way; the .380 doesn't have the reliable stopping power to rely on for a self-defense caliber. You need to move up to a 9 mm, .40 S&W, or .45 ACP.

Second way; the small caliber gun you actually will carry is better than the large caliber gun you leave at home because it is too heavy, bulky, and hard to conceal.

I don't think there is really much more to the argument than that.
