Band's hit (4)
I believe the answer is:
belt
I believe this clue is a double definition.
'band's' is the first definition.
(I've seen this before)
'hit' is the second definition.
(belting is a kind of hitting)
(Other definitions for belt that I've seen before include "Zone -- thrash" , "See 18" , "Hit - trousers' support" , "See 24" , "Strap" .)
