The poor fit is normal and fairly common. Before you buy a new set you may want to try them on your bayonet as they may be nearly as bad as what you have now. However, yours is about as bad as it gets. I have seen bayonets with one side fitting well and the other being loose. Wartime tolerances were on the broad side to try to keep hand fitting to a minimum although I have M1icon bayonets where one or the other of the grips has obviously been filed to fit.
