I carry my LCP every day all year. It's not a very sexy beast. It's not something that I ENJOY shooting. It doesn't give me the ultimate warm-fuzzies regarding caliber.
But, I shoot it well. It packs better than any other gun I own. It allows me to follow rule number one of being in a gun-fight. In short, if I am going somewhere where firearms are permitted to be carried, the LCP tags along.
In the fall/winter I just add a gun to go along with it. My work attire in the summer prohibits me from carrying anything bigger than a pocket pistol.
