Many years ago when I still worked behind a gun counter the shop got a phone call from a concerned husband wanting to get his wife a .25 auto for personal protection. The owner’s response: “How good is your divorce lawyer?”
Now as this post at The Smallest Minority illustrates, that doesn’t mean the .25 auto won’t work. Just that it’s not the best tool available for the job. With the Kel-Tec and Ruger .380s I would opine that the .25 is on its way to joining to Dodo bird and if it isn’t, it should be. Given the choice I’d rather have a compact 9mm or .38 special as a minimalist firearm, but sometimes the compact .380s are the best you can do.
