so let's say (somehow, it doesn't matter how I don't think), gunpowder weapons become somewhat widespread in Europe (Hand cannons to be exact), enough so majority of the soldiers possess a gun and the knowledge to operate it. So in 1241 when the Mongols come knocking, they find themselves up against hand cannon-wielding Polish and German soldiers arrayed against them.
how would this impact Mongol conquests, and their campaigns against Europe?
