You get over worrying about carrying in time. I swear the more you open carry, the more other people do. I normally conceal, but if I'm about to go somewhere like the range, or hunting, just wandering in general, you bet I open carry. Next day there is a good chance I'll find someone also open carrying. You can beat the reasons for any carry method to death. To me I conceal most of the time for one simple reason. I don't want those who do not like firearms to be uncomfortable. As weak as that sounds, you are always at a huge advantage when people like you.
IWB is worth trying. I have yet to meet anyone who ever did it for more than a short while before giving it up. I've never known anyone who carries IWB every day for years on end. I must have given it a month or two, and 3 holsters before I realize I hated it. If I'm wearing jeans, I use an OWB holster strong side. Sometimes I'll pocket carry. I made a decision to choose holsters that worked with the clothes I already wore. I wasn't about to become "vest guy" at 21 years old just so I could conceal a handgun. Most of the year I wear nothing but a T shirt, and there are holsters that allow you to conceal medium frame revolvers under a T shirt. I far prefer my 3" SP101, but I can just about conceal my 5" barrel GP100. The bottom of the holster shows when bending over. A 4" K frame is doable.
