By the time the US started loading the M1909 cartridge most of the fighting in the Moro Insurrection was over, any remaining fighting was being primarily done by the Philippine Constabulary, and most Peacemakers had been withdrawn from service.
I sincerely doubt if the M1909's wider rim was intended to prevent it from being used in the Peacemaker. It could still be loaded in the gun, just not a full 6 rounds.
