What does the gun represent?

Seeger’s acquisition of the German-made Luger is described
in paragraph 84. The gun represents a victory for him and a symbol of justice (paragraph
121), and it also represents a possible armed response to anti-Semitism (paragraph 122).
As a means of gaining the $65.00 that would permit the men to have a good time, it is
potentially a source of conflict between Seeger and his friends. The climax of the story
(paragraphs 141-48) occurs when Seeger decides to sell the gun; it causes the resolution
which is the story’s major act of faith.
