OK, I'm stupid to the term. What's a "Hillary Hole"?
A place Bill apparently avoids if at all possible.
I have both and would be hard pressed to pick one over the other. I guess if a model 19 and a GP-100 (or one of my security six's) were laying on a table and I had to choose one to carry while crossing the Gobi Desert Or some other out of the way place I would pick the security six or the GP-100. But a good flap holster would make either one OK for the trip.
