A. He pulled a gun on me. (a dictionary sample sentence)
B. The story is told of a priest who was coming back to his parish house one evening in the dark only to be accosted by a robber who pulled a gun at him and demanded, “Your money or your life!”
(Kelvin, The Redemption of our Human Nature, from a web site.)
Is this difference in the choice of the prepositions related to any differences, if there were any, in his determination to harm or in the way of aiming at the target?
Thanks in advance
You PULL a gun ON someone.
You POINT a gun AT someone.
"Pull at" has a different meaning as a phrasal verb, meaning almost the same as "pull". Examples: "Stop pulling at your hair. It will fall out." "The child was pulling at my sleeve to get my attention."
