I do both. I live in a small desert town (Pop.11,000) in Arizona. We have a lot of grazing land around town. We move cattle from one section to another the old fashoned way, on horseback. We all open carry a pistol. Sometimes we go have lunch at the local cafe. We all open carry. Whenever I go out in the desert, which is often I open carry a Ruger P90, 45 ACP. I load two snake loads and 7 hollow points. Hard to conceal a Ruger P90. Basicly a "Brick with a trigger" but it will cycle anything consistantly. The rest of the time when I'm in town I carry a Makarov or a PA 63 concealed. It gets real hot here, (110-115) and shorts and tee shirts are uniform of the day and these small frames conceal nicely. Point is that even in an isolated desert town there are very few who OC in town except when working, but most CCW. I'm not advocating one over the other, just relating real life experience.
