Since I can't carry at work, and I spend most of my non-work time doing odd jobs on my property, the handgun that spends the most time on my person is my NAA Black Widow. I don't carry it to protect myself from bad guys; rather, I'm hoping to have an encounter with the feral tom cat that has been taunting me for months.
If I'm away from the homestead I'm most likely to have the Model 642 that I picked up last Friday. Before then it would have been my Model 60.
