They get hot, of course, shooting (4)
I believe the answer is:
guns
'they' is the definition.
Both the answer and definition are plural nouns.
Perhaps you can see a link between them that I don't see?
'hot of course shooting' is the wordplay.
I cannot really see how this works, but
'course' could be 's' and 's' is located in the answer.
The remaining letters 'gun' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'get' acts as a link.
Can you help me to learn more?
(Other definitions for guns that I've seen before include "Snug weapons?" , "Bangers" , "Firearms" , "Transportable armaments" .)
