A less common way to go, using a revolver more or less (8)
I believe the answer is:
tricycle
'a less common way' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tricycle that I've seen before include "Child's three-wheeler" , "easy ride?" , "transport for children" , "wheeled transport" , "Three-wheeled vehicle" .)
