Are you asking about fitment, or for accuracy enhancement?
For fitment, no most any forend will fit any barrel. Actually they are cut for the biggest barrels so the smaller skinny ones get the "gaps".

For accuracy, Gendoc told you right. Gotta shoot it to really tell. Most show improvement after a good fitting, while others need nothing.
FWIW, Its been my experience that proper forend fit followed by proper and consistant latch engagement are the two biggest contributors to better accuracy with a handi.
Good luck,
