Weapon raised shot a spymaster (7)
I believe the answer is:
sidearm
'weapon' is the definition.
(type of gun)
'raised shot a spymaster' is the wordplay.
'shot' indicates an anagram.
'a spymaster' becomes 'M' (M is the head of MI6 in James Bond).
'raised' with letters rearranged gives 'sidear'.
'sidear'+'m'='SIDEARM'
(Other definitions for sidearm that I've seen before include "One may be fired" , "Officer may carry this" , "weapon" , "Piece" .)
