Reading some of the other experiences posted around here, I holstered up when I made a run to Walgreens today at lunch to pick up a few essentials. All I can really say about it is . I think only two people even noticed; one was foreign (speaking some sort of Russian) and generally looked pitifully sick; the other was a dude in a pink shirt, who did little more than glance down and then went about his merry way. Even the lady at the register didn't cast a glance. All in all, a relatively uneventful event.
Macktee didn't notice my Glock 23 on the dash of my car until I got out and stopped at an ATM and was OCing.
