Victor out West is a pretty good shot (5)
I believe the answer is:
inner
'a pretty good shot' is the definition.
(I've seen this before)
'victor out west' is the wordplay.
'victor' becomes 'winner' (synonyms).
'out' is a deletion indicator.
'west' becomes 'W' (abbreviation).
'winner' with 'w' removed is 'INNER'.
'is' is the link.
(Other definitions for inner that I've seen before include "red" , "(Hit on) part of target immediately next to the bullseye" , "may not satisfy this man" , "Ring round bulls-eye" , "Hidden" .)
