The winner will not have to travel to go to the builder, unless he wishes to and he/she lives near by.
the winner can post the molding he/she makes of his anatomical shape to the builder.
im sure teh builder will be able to 'carve' the handle to the shape of teh mold, given by the winner...or at least it will be an 80% perfect personal fit, instead of a universal one...
and believe me, if you have used a universal handle and then a personal anatomical one (ON THE SAME GUN) you will know the difference...
surely it must be made of wood and not other moulding material (the finished product) to keep the wood 'magic' look !!
