That's where I started on the decision tree, back in 1993 when Ruby Ridge and the Klintonx' assault on the Davidians (masterminded by Poppy Bush and his cookie-pushing internationalist pals) got me to thinking that a Big Grab was in the works somewhere.
So I went with a) concealability and b) controllability. The .380/9mm Luger complex was about where the curves all met. The nines are just a weee bit too pudgy and hard-to-hide (and recoil-rich, in the small frame format), and the .32 ACP hideaways just a little bit too lean and light-hitting.
The warmer .380 loads and 9mm Makarov would seem to be the optimal compromise -- it seemed to me. And still does. Need one-shot stopping, absolutely, every time? Get a shotgun and forget about concealed carry!
Yeah a shotgun will come in the future. I have what I feel comfortable with now. I will definitely add a shotgun to it though.
