Caliber/gun choice for concealed carry
I'm sure this question has been asked 1000 times, but I can't find what I am looking for by doing a search. After a recent uncomfortable situation my wife and I had while traveling, I have decided to get my concealed license and carry in my truck. My question is, what caliber/gun would you choose? My idea is to keep the gun in the console of my truck and only carry occasionally on my person. I would prefer to go with a semiauto over a revolver. I currently own a .357 mag with a 6 1/2" barrel, so it is too big to carry. I also plan to rent several guns and try them out before buying, so I am just looking for a starting place. Thanks for the help.
