I've had one for a while. I really liked it when I didn't want ANY sign that I was carrying.
Later on I bought a K&D for carrying in my back pocket, and planned to use it most of the time but use the pager pal when I wanted it well hidden. I have since seen the error of my ways! ;D I now almost exclusively use the K&D in a front pocket carry. It's well hidden and much easier to get to than the pager pal. I'm not trying to hijack your thread, just pointing out what I found.
Back to the pager pal........ it does work fairly well. It takes some time to get use to the draw; two hands, etc. I modified mine just a bit. I actually made a cut in the leather where the "pager" clamps onto it so that the holster "rides" a little bit lower. I felt that it concealed a little better and yet I still had no problems with the draw. But I'm long waisted and wear my pants fairly loose. It might be different for you.
Anyway.... just my .02 worth.
