What's the best scope mounting system out there for the 29?

I am ignorant on pistols.

i like the b-square base. it slids into the rear sight slot and clamps onto the barrel. i had a red dot on mine.

If you have one of the new 629's go with the Leupold that replaces the rear sight, as the gun is already tapped and drilled under the sight for the base.

Aimtech makes a neat one that has a hole bored through the base so you can still use your front sight with the flourescent rear insert provided.
