Yes. Personification is the literary device that occurs when a material object that does not possess vital qualities is described using adjectives that usually pertain to the living. Personification can also take place when inhuman objects act in a way that is only possible for humans. In this example, "stolid" and "undaunted" are adjectives that are typically used to describe human personality, making it personification when they are used to describe something as inhuman as a gun. Moreover, the guns "speak," an action that is only available to living beings.
