More offensive than Jenkins' subjectivity is his misspelling Randolph Scott.
"Every gun makes its own tune." Blondie's statement late in the film after hearing gunfire in the town destroyed by cannonade, indicating that he now knows Tuco is close by. But the gun Tuco is using at this point is one he acquired after parting company with Blondie, so Blondie has never heard it fired before. How then is he able to recognize Tuco's weapon? Hanley offers a solution: it is not the sonic properties of the pistol, but the rhythmic firing pattern that gives Tuco away. "A distinct pattern of pistol shots is heard, five shots in rapid succession, a pause, then a final shot [this 5:1 pattern is the signature of Tuco . . . ]" (p. 313). Hanley hears that pattern in the film's opening shoot-out (involving Al Muloch and company), and sees it demonstrated in Buffalo Wallow when Tuco takes target practice with the wooden Indians. Perhaps, then, Blondie's later reference is not to Tuco's weapon; Tuco himself is the "gun."
Let's call it instead some kind of continuity error. That makes more sense.

You are the most boring man alive.
