How would anyone know as I don't think many of these are in circulation? But I admit its not an area I follow. But how much are they claiming they shoot low? To adjust yours suggest these steps, shoot it, decide how much you have to move and in what direction, measure the existing sight heights and then compare to the height table. an 8 rear is .250 and a 6 front is .230 which should give you some idea on the baseline. Front sights in theory move and inch rear sights in theory move two inches. Good luck on finding any of the bigger numbers in the supply channel...
