Well, if you're new to open carry or carrying in any condition, why not just go OWB and throw a cover garment (shirt) on?
Works well. Is comfortable. Easy access. And if you feel the need to open carry, just take your cover garment off!
This man has an H&K .40, a Glock 30 (45ACP) and two spare mags on him, all on the belt and out of sight.
Don't make this any more difficult than it needs to be.
You don't have to put guns in your pants to go out in public!!
