* Like gun ready to fire? (6)
I believe the answer is:
loaded
'like gun ready' is the definition.
'loaded' can be an answer for 'ready' (thesaurus). I am not certain of the 'like gun' bit.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for loaded that I've seen before include "Laden; rich" , "drunk- > biased" , "Wealthy (slang) - charged" , "Burdened - with lots of money" , "Burdened; rich (slang)" .)
