I have a Kel-Tec .380 that I carry almost everywhere in the warm months. I'm thinking of getting the Kel-tec 9mm for more fire power but it is a little bit bigger. Do you guys think the trade-off from smaller size to more power is worth it? I don't use a holster with the .380, I just put it in my pocket for pretty deep concealment. Does anyone have both the 9mm & the .380 that might have a comparison on concealment for me? Or does anyone just have the 9mm that they put in their pocket without a holster?
