I use one alot, and have for several years. It's a brown nylon Euro-Pak, with 3 large zipper compartments, not a purpose made gun carrier, but the second compartment is large enough to carry a very large handgun and extra ammo, while my wallet stays in the front compartment along with a small knife.
It's carried a full size 1911, a 4" Smith .357 magnum, and now carries a Smith 59 series auto with an extra mag.
I'm also an old fart with glasses and more hair on my face than on top - I'm not seen as a threat either, which is OK with me.
I also occasionally carry a backup in the left front pants pocket, usually a Keltac P32.
I have several fanny paks, all marked with logos from sporting goods makers.
(North Face, Adidas, etc.)None of them look "tactical", and I do practice with them at the range on occasion.
