Usually Ruger 1911...
Sometimes around the Farm, a Blackhawk or Super Single Six.
If going to town, or for work, a Sig 365L.
Mostly OWB not particularly concerned with concealment. Wear a un tucked shirt and go.
A ultralite .38 snub is often IWB with a reload in front pocket, if the tool belt comes out. It seems to work the best for me.
