When you mirrored the drafted grip, it created a parting line along the top of the grip. Smooth the parting line by adding a constant radius fillet.
Click Fillet
on the Features toolbar and select the edge shown.

Under Fillet Type, select Constant radius.
Under Items To
Fillet, set Radius
to 5.
Make sure Tangent propagation is selected, so that the fillet extends along all of the segments of the edge.
Click OK
