When I was carrying more regularly than I do now, (dratted work) I usually carried a Government Model .45, but always carried a Kel-Tec P32. Why? Because there are limits to what outfits I can wear that will cover a full sized gun. Most of the time, I can do it, but there are limits. Sometimes it's it's hot out. Sometimes you just want to look good, and want to wear a fitted jacket instead of a potato sack.
The tactical gurus would have us all carrying two full size pistols, a knife, a tactical light, a couple of reloads, a cell phone, and probably a major trauma first aid kit. There may be people to whom such a combat load strikes a reasonable balance against their threat profile to make it their EDC. I'm not one of them.
But, I'm also not one of the people who say "I don't feel under gunned with a mousegun.". I definitely do feel under gunned with one. I know what I can do with a real gun, and it's a lot better than I can with a pocket pistol. However, when faced with a 100% chance of being hot and miserable under batman's equipment belt and enough of a cover garment to keep it under wraps, and a one in ten thousand chance of actually needing the pistol, quality of life concerns tend to control.
