I remember cutting up hundreds of Airweight Chiefs at MCAS Futenma back in 1975 or so. They were being decommissioned as the aircrews were going to .45s. Made me sad.
I don't carry an Airweight much anymore, but I did 24/7/365 for work way back then. It was good to have handy. These days, if I'm in a state where I can carry concealed, it's a 351PD in .22WMR. Don't needed anything bigger, but if I really, really needed something bigger I'd carry a rifle.
