What I own and what I carry are very different. I own a very small .22 auto, I can't recall what kind right now, darn, my mind is a blank! It's not Stevens, but I think it starts with an "S".
Anyway, I never carry it. It belonged to my old man and I got it when he passed away. I carry a Ruger P345, and that's about the smallest thing I am comfortable with.
The Ruger LCP .380 but not real crazy about trigger pull other wise I carry the SP101. Want to try a Bersa Thunder .380 think I would like it but so far haven't been able to handle one.
right before the .380 vers came out, i bought a kel-tec P32 - .32 caliber. I can't get rid of it now to save my life. guess its a keeper by default.
now i EDC a .357 LCR.
CM9 I will not carry smaller then a 9mm, just do not believe it will work well "enough". That said I believe the best gun you can have is the one on you when you need one.
I carry a S&W Bodyguard 380 from time to time.
9mm Shield is my EDC. The 380 is handy to throw into a cargo pocket for a quick trip out, without having to put on the IWB holster.
