I carry pretty much every day now, at least where I can legally... Pretty new to EDC myself... Looked at all sorts of holsters and places to carry. Went from shoulder holster to small of back to appendix to you name it. Didnt like the idea of shoulder carry and sweeping everyone behind me with a horizontal one, also I wear t shirts a lot in the summer. didnt like the idea of appendix carry and sweeping my leg and possibly femoral artery all the time since i prefer to carry with a round chambered now. Eventually I decided that I prefer to carry strong side at 4 o'clock ish (most comfortable for me considering I carry an M&P9c). Just ordered a custom sharkskin holster that is IWB and also OWB when removing the belt loops, that way I can change it up a bit depending on what I'm doing.
Best advice I can give, coming from a newcomer, is if you carry at the waist, get a good gun belt! It helps tremendously, even for IWB
