Weapon put out front (8)
I believe the answer is:
crossbow
'weapon' is the definition.
(crossbow is a kind of weapon)
'put out front' is the wordplay.
'put out' becomes 'cross' (both can mean angry or irritated).
'front' becomes 'bow' (the bow is the front of a ship).
'cross'+'bow'='CROSSBOW'
(Other definitions for crossbow that I've seen before include "Old weapon with mechanism for firing arrow" , "Old weapon of war" , "it could be wounding" , "can precipitate a quarrel" , "One responsible for shooting bolts" .)
