The best handgun to carry if you could have only one gun, is the gun you would actually carry.....
A gun will do you no good if it is left at home or in the car, that is if you are serious about personal protection at all times......
Good advice
“is the gun you would actually carry.....”
And thats why I have a little .32. My .45s are too hard to carry concealed in shorts and a tshirt.
