Well, one plot twist could be that Naruto initially mistakes the guns for some strange new ninja tools. He might try to use them in his own unorthodox way, like combining his chakra with the gun's mechanism. Another could be that the guns are part of a plot by a new enemy who has somehow brought modern - day weapons into the ninja world. This would force Naruto and his friends to adapt to a completely different type of combat. Maybe Naruto would be the only one who could figure out how to stop these guns from being used against the village because of his unique ability to think outside the box.
A possible plot twist is that the guns are cursed items. When Naruto picks one up, it starts to affect his mind, making him more aggressive. His friends would then have to find a way to break the curse before Naruto loses himself. This would add a new layer of drama to the story, as Naruto is usually the one saving others. Now he's the one in need of saving, and it would be interesting to see how his friends handle the situation.
