No gun nut/carry people aren't the only ones who will notice them. Thugs will too. That's why I don't like them. But in one sense you're right. The sheeple will never notice.I noticed a senior in my area carrying with one of these. At that very moment it dawned on me, the only people who will look at this and know someone is carrying are gun folk that wouldn't care in the first place.
It's not my cup of tea, but if it's what gets you to carry when leaving the house and you're comfortable with it, then by all means. The best gun and holster is the one you'll always leave the house with.
