Question about support loops for smooth objects

16bit

I need help smoothing the trigger hole of this colt python. The traditional support loops creates creases, and trying to smooth those creases create different creases. How am I supposed to get the tightness the support loop provides with maintaining the smoothness of the area around it.

The mesh in blue wires is the mesh in question.

Looks fantastic, I will try this asap.

Minor pinching but nothing that can't be solved by moving verts. In any case its a vast improvement. Thank you Coots.
