I carry a Black Widow in .17HMR. 20 feet I can put 5 in the head off hand as fast as I can with my S&W m38. At 1500 fps, that's gotta sting. Carry it as a second gun or when I'm in shorts or sweatpants. Also carry around the home, mowing the yard, cutting fire wood, gardening, etc. So light and small you don't even know it's there.
