Pearl of Ineffable Knowledge: PC Save/Quit Method?

Title, I haven’t gotten to the end of the quest yet so I don’t know if it works. Can you get to the point of turn-in, go to clap, see what pearl you’re gonna get, and quit before turn in until you get one you want?
I guess the modifiers on it really don’t matter in the grand scheme seeing as though the best rolls are fire rate and mag size.
