I ran into a post in a thread here where someone was thinking of up sizing their concealed carry piece in size and caliber in response to the recent Colorado incident. I'm wondering if anyone else is or considering it at least. Or has in the past because of a shooting or event such as this one. Personally I am not but that is only because I already believed in carrying enough gun and that any handgun is just a tool to allow you to fight back to your shotgun or rifle if things really do go bad. Simple question I guess is with your current concealed carry piece would you regret not having a different handgun or revolver on you if you were present in an active shooter situation?
