Injury that puts an end to the shooting (3)

I believe the answer is:

cut

I'm a little stuck... Click here to teach me more about this clue!

'injury' is the definition.
(cut is a kind of injury)

I don't understand the rest of the clue.

(Other definitions for cut that I've seen before include "Reduction in power" , "Fail to attend" , "Reduction; piece of meat" , "Cold-shoulder" , "Cross" .)

I've seen this clue in the Evening Standard.
