Kid's toy guns distributed with hesitation (9)
I believe the answer is:
youngster
'kid's' is the definition.
(synonyms)
'toy guns distributed with hesitation' is the wordplay.
'distributed' indicates an anagram.
'with' says to put letters next to each other.
'hesitation' becomes 'er' (sound used when hesitating).
'toy'+'guns'='toyguns'
'toyguns' with letters rearranged gives 'youngst'.
'youngst'+'er'='YOUNGSTER'
(Other definitions for youngster that I've seen before include "Person of tender years" , "Rug rat in New York" , "Youth" , "Child, minor" , "Kid" .)
