Weapon hurt one of Macron's (4,3)
I believe the answer is:
stun gun
'weapon' is the definition.
(type of weapon)
'hurt one of macron's' is the wordplay.
'hurt' becomes 'stung' (sting can mean to hurt).
'one of macron's' becomes 'un' ('un' in French - French president Emmanuel Macron).
'stung'+'un'='STUN GUN'
(Other definitions for stun gun that I've seen before include "Taser possibly" , "Immobilising weapon" , "Police weapon" .)
