Admires new weapon (7)
I believe the answer is:
sidearm
'weapon' is the definition.
(I've seen this before)
'admires new' is the wordplay.
'new' indicates anagramming the letters.
'admires' with letters rearranged gives 'SIDEARM'.
(Other definitions for sidearm that I've seen before include "Officer may carry this" , "weapon" , "Piece" , "One may be fired" .)
