Comfortable about stolen report (7)
I believe the answer is:
Here is my best explanation:
'report' is the definition.
'comfortable about stolen' is the wordplay.
'comfortable' becomes 'snug' ('snug' can be similar in meaning to 'comfortable').
'about' says the letters should be written backwards.
'stolen' becomes 'hot' (I've seen this before).
'snug' backwards is 'guns'.
