I've seen so many different opinions on here about what calibers are acceptable for self defense and most seem to believe that the smallest caliber they'd go with is 380, and some say no smaller than 9mm. I have a friend, or actually more like an acquaintance that carrys a Keltec .32. Also how big of a difference is there betweem the .32 and 380? 380 is what I carry at the moment and all I have for now, but I don't think I'd want to go any smaller. I do feel safe with the 380 though.
