Average weapon in a manner of speaking (8)

I believe the answer is:

parlance

'in a manner of speaking' is the definition.
(I've seen this before)

'average weapon' is the wordplay.
'average' becomes 'par' (average score in golf).
'weapon' becomes 'lance' (lance is a kind of weapon).
'par'+'lance'='PARLANCE'

(Other definitions for parlance that I've seen before include "Idiom" , "talk!" , "Conversation" , "Way of using words" , "Language" .)

I've seen this clue in The Sun.
