Anybody have one?  Does it really look more like an honest to goodness fanny pack, or does it scream "gun"?

I've got what's called a medium, I believe.
Mine is black with a grey panel on the front.
I added some different colored zipper pulls, the kind made from climber's utility cord with a plastic tab on the end.
I was planning on adding a patch of some sort with a easily recognised logo like Nike or some sort.

The shape is square-ish, it has a wide belt, and two large black buckles on either side.

I would say it screems GUN to me, but that's because I watched the progression of these packs over the years.

To a non-gun person... I have no idea if it screams GUN.
I have never had anyone comment on it.  I wear a couple of different fannypacks for times when I'm running, biking, hiking, or sometimes just around town.
I've never had anyone act in a way that made me think I was wearing a 'fag' anything, or carrying a gun.
So, I guess it works!

I can just get my Glock 30 into it and zip up the back.

Most of the time, I wear a second shirt over my t-shirt and the outer shirt draps down over the fanny pack, so that might help also.

It is well made, and I can draw fairly fast from it.
I can do it with either hand.
