Carry, with some hesitation, an automatic pistol (5)
I believe the answer is:
luger
'an automatic pistol' is the definition.
(I've seen this in another clue)
'carry with some hesitation' is the wordplay.
'carry' becomes 'lug' (lug can mean to carry).
'with' means one lot of letters go next to another.
'some hesitation' becomes 'er' (sound used when hesitating).
'lug'+'er'='LUGER'
(Other definitions for luger that I've seen before include "Shooter" , "Weapon" , "German semi-automatic pistol" , "Type of (German) automatic pistol" , "Make of pistol" .)
