Try to get fired (4)
I believe the answer is:
shot
This clue is a double definition.
'try' is the first definition.
(shot is a kind of try)
'fired' is the second definition.
(shooting is a kind of firing)
'to get' is the link.
(Other definitions for shot that I've seen before include "Wounded" , "streaked with colour" , "Woven in different colours; attempt to score" , "Try -- ammunition" , "Slug" .)
