Thinking of a Galco Waistpack - Escort model. Does anyone have any experience with this type holster? Have Sig232  and Beretta 92F. Currently carry one or the other with IWB or Hip holster. Thinking WaistPack might be way to go if not wearing jacket or shirt to cover the carry.

My cop pals always told me the sight of a fanny pack always spells "GUN" to them.  
They suggested a bright color instead of black and putting a sports team logo to help hide it in plain sight.  (With a CCW of course)
I bought a bright blue Uncle Mikes version that USPSA was offering a few years ago.  Put a UK Wildcats patch on it.
One thing though, these things are slow on the draw and the muzzle stays close to the jewels if worn in front.  I carry mine on my side as access is faster (for me) and much safer from there.
I'll take my Blade Tech IWB and a vest any day.  The only time I wear the fanny pack is on vacation in warm climates.
