Loaded a firearm at the front -- easy (8)
I believe the answer is:
'loaded' is the definition.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for affluent that I've seen before include "Very well off, quite rich" , "comfortable" , "Wealthy, rich" , "Flute fan may be wealthy" , "Well-heeled" .)
