For her, being able to deliver all 13 rounds on target in a very short time frame (which she could do) was a significant advantage over delivering only a few 9mm rounds. My mistake was not recognizing that. Thankfully, I failed to get her to change. She knew her needs better than I did, and if we were to have that discussion today, I would simply help her become as competent with her gun as I possibly could. I understand the issues better and have reined in my macho opinions.
If I had to choose between a micro 9mm and a .380 in the same size and weight class, I might choose the smaller round if the difference in controllability were significant. In the case of the test gun I mentioned earlier, I’d frankly rather have a .380! Yes, it was that bad. Yet the gun sells well and the manufacturer reports they can’t keep up with demand. I’m positive that many of those buyers are making a bad decision, and probably for the wrong reasons.
Before you sneer at that lowly mousegun, stop and really think about the job it is intended to do. Understand the real task: to get combat-accurate hits, with an effective bullet, on target as fast as you can get them. In some cases, that “little” .380 might be better at the task than anything else.
