Will Sao sig 220 Hogue grips work on a 220X6. Looks like a mag funnel will be needed, screw holes look the same, slide lock and safety cut look the same. Anyone see a problem I haven't considered?

They can work but it will require several modifications by a competent machine shop or a hobbyist with a CNC. The X-Six grip is a dual plane while the Hogue grips are single plane(has flat sides).

Not worth the effort. I'll shoot these, and if the get trashed, I'll spring for a new set. Thanks
