I run a Beretta with a moderate beaver tail. Developing the "non-claw the shit out of my stomach grip" is a priority for me.
I find that it is a "touch point", more-so than an "anchor point". You're thumb dwells on the "hammer" or wrapped over the beavertail for just a split second before it folds down between the body and gun during the draw.

This is def. good for a solid .25s.
