LAMAR G,
On firearms not equiped with adjustable triggers the two most common methods of lightening a trigger is: 1) Replacemenr of springs with lighter springs. 2) Removal of metal on the sear or trigger. I sounds as if the person who did the work used number two and that is exactly what the results were, number two. Unless the person has a very good reputation in your community, I wouldn't go back to him. While any good gunsmith can, and do, make mistakes, I'd be leery about what would happen the second time. Good luck.
