A thigh rig or a regular belt holster with a drop or jacket slot might work for you. Since you mentioned usually only carrying it out around the farm. The drop or jacket slot will keep it from pinching at the waist or pushing against your side. I agree on some of the thigh rig concerns, but it doesn't sound like having to protect your weapon from being taken away etc.. would be an issue for what you're looking to do. If you go for the carrying in a traditional belt holster get a good belt that has a spine so it doesn't sag. I wouldn't think an IWB would be the best for carrying around the farm.
