I've used a fanny pack on occasion
With our budget being so tight these days, I no longer have $100 for a new holster. I'm wanting to carry concealed again. Recently I employed a dark brown leather fanny pack for my 92FS and wore the rig with dark dockers and under an untucked Hawaii type shirt.
It was more comfotable than my Galco leather holster for my GP100, which I doubt i could've effectively concealed, even under my photographer's vest. Here in Louisiana we have "open carry", but I'm not prepared to undertake this just yet.
