I carry a KelTec 3AT a lot because there is almost no time that I can't carry it. It drops in my pocket and is unnoticeable. The cartridge is considered "marginal" by most experts. However, like the old saying goes; "The best gun to have is the one that you're carrying when you need it". IMHO, Having a gun and being able to be accurate with it is far more important than what you carry.Like the title says, why do folks own a .380 caliber weapon? Is it the size of the pistols, an advantage to the cartridge, or what?
