This is actually a really good point. Assuming you aren't taking a stroll in a crime heavy area and you don't actively look like you are up to no good, you should be able to do this all day long without anyone noticing or caring. Illegal? Well, yeah. But the risk is so low as to barely register. There are a lot of otherwise law abiding folks caring without a permission slip. Of course, the penalty for screwing up is pretty high. Risk/reward is a very personal choice.Assuming you're in a typical MD suburban area, put the gun in the holster and go for a nice long walk around the neighborhood. That should give you a good sense of how it's going to feel and ride as you move around some in a pretty low key environment.
