i for one do not know of , nor do i think an after market trigger for the model 94 is available ( not saying that there aren' t , just i haven' t heard of any ), as for a gunsmith working on it , i think it would be a better idea to ask one of your smiths if they' de be willing to do it , a lot of smiths will shy away from trigger work for fear of a liability lawsuit if an accident were to occur but , like i said , see if one of your local smiths would be willing to do it , or might know of somebody who would be able and willing to do it for you
