Hi, everyone! I'm trying to model weapon from this concept:

Now working with hi-poly part:

But now i'm really confused with one issue. I'm trying to model side ball shape next way - i splitted edge loops and extruded them inside of the ball:

Now i need to create plane on pistol drum side and really don't know how to do it wright.
You can see problem on printscreens i prowided below.



Decision that I made is not satisfied me at all.
Will be happy to hear any advice how to fight this issue.

And if you are using subsurf, try making the faces all-quad (the quad part of quad chamfer only applies to the chamfer itself - not the surrounding geometry).
Thank you for advice, i used triangle, as on first image you send, and result satisfied me. I'm very grateful to you for response.
