Weapon of Shakespearean character (6)
I believe the answer is:
pistol
This clue is a double definition.
'weapon' is the first definition.
(pistol is a kind of weapon)
'shakespearean character' is the second definition.
(I've seen this before)
'of' acts as a link.
(Other definitions for pistol that I've seen before include "pop" , "Hand weapon" , "Shakespearean - weapon" , "A small hand-gun" , "Hand-held firearm" .)
