Shot from gun (6)
I believe the answer is:
cannon
I believe this clue is a double definition.
'shot' is the first definition.
(cannon is a kind of shot)
'gun' is the second definition.
(cannon is a kind of gun)
'from' is the link.
(Other definitions for cannon that I've seen before include "Big gun" , "mortar" , "shot playing billiards" , "military weapon" , "The large gun sounds like a church dignitary" .)
