Gun I tried out could make you very interested (9)
I believe the answer is:
intrigued
'very interested' is the definition.
'intrigued' can be an answer for 'interested' (intriguing is a kind of interesting). I am unsure of the 'very' bit.
'gun i tried out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'gun'+'i'+'tried'='gunitried'
'gunitried' is an anagram of 'INTRIGUED'.
'could make you' acts as a link.
Can you help me to learn more?
(Other definitions for intrigued that I've seen before include "Becoming interested" , "Keenly interested" , "Having curiosity aroused" .)
