Just an FYI and Tip of the Hat to Melody Lauer:

Bought these Dr. Scholls Womens gel inserts at WalMart, about $5.
I attached one of the pads at the bottom of my P30SK holster with some Velcro. It tucks the holster in slightly, and cushions it right where the base of the holster rests against the point of my hip. Plus being rubber it seems like it 'locks' the holster to the fabric of my cargo shorts.
(I seem to have gravitated to 'just forward of 9 o'clock as most comfortable for me. Combined with some recent weight loss, I have a sort of hollow in this area.)
