Why are you so concerned with peoples choice of caliber?
Show me a 9mm that is as small and light as an LCP or M&P Bodyguard and then tell me that they have no place. Sure there is the Robaugh 9mm, but not only are they costly, but recoil in a gun that small chambered in 9mm is over the top.
You claim there are many quality 9's of the same form factor as .380s, well look at the LC9 vs LCP, or the Shield vs Bodyguard. There is a big difference in size and weight between the two, enough that these small .380's have their place when you need extra concealment.
While my EDC is a 9mm Shield, at work I carry a M&P Bodyguard .380 in my pocket. I have to wear a suit and tie everyday, and often take my suit coat off in the office. I cant carry IWB and the Shield is too big to carry in my pocket and too uncomfortable. Tuckable holsters aren't an option either, suits and dress shirts are supposed to be form fitting, I am not about to wear a pants size and shirt size up in a suit to accommodate a handgun and holster when I can easily carry a small .380 in my pocket. Part of my job is putting off an image of professionalism, wearing pants and a shirt that are too big take away from that image. It's sad that in the world we live in people judge you by your appearance, but that's the way it is and it's not going to change. So for me, the .380 is my best choice at work.
Is the .380 the best round for personal protection? Absolutely not. Is it an adequate round? Absolutely. To claim they don't have their place is ridiculous.
