Gun man (5)

I believe the answer is:

piece

I believe this clue is a double definition.

'gun' is the first definition.
(piece is a kind of gun)

'man' is the second definition.
(synonyms)

(Other definitions for piece that I've seen before include "Castle, perhaps" , "Musical composition" , "See 3" , "Chessman - part - firearm" , "constituent" .)

I've seen this clue in The Independent.
