Before midday the doc gets shot (4)
I believe the answer is:
ammo
'shot' is the definition.
(ammunition)
'before midday the doc' is the wordplay.
'before midday' becomes 'am'.
'the doc' becomes 'mo' (I can't explain this - if you can you should believe this answer much more).
'am'+'mo'='AMMO'
'gets' is the link.
Can you help me to learn more?
(Other definitions for ammo that I've seen before include "Bullets (sl.)" , "that goes in magazine: ...?" , "Bullet" , "rounds briefly" , "Projectiles" .)
