Fruit stolen for ammunition (9)
I believe the answer is:
grapeshot
'for ammunition' is the definition.
(historically a type of ammunition)
'fruit stolen' is the wordplay.
'fruit' becomes 'grapes' (grapes are fruit).
'stolen' becomes 'hot' (stolen goods are 'hot').
'grapes'+'hot'='GRAPESHOT'
(Other definitions for grapeshot that I've seen before include "Great Balls of Fire" , "one could get peppered with it!" , "Small projectiles fired from cannon" , "Describing ammunition" , "slugs?" .)
