I carry my Bodyguard 380 in the watch pocket of my jeans all the time. In the winter I carry it as a backup to my XD40.
FBI stats say the average gunfight includes three rounds fired over three seconds from a distance of 3 yards.

With that said, in most cases a .380 is sufficient. However, we all know that the bigger the better and a bigger caliber has more stopping power.
Proficiency in any gun greatly increases your chances of surviving a self defense scenario. In the right hand a .22lr is deadly while in the wrong hands a 44mag would be unless. Practice practice practice....... IMHO
Those "statistics" are very misleading and should not be taken at face value.
Beside, who says you are going to be dealt the "average gunfight"?
