Number one , all should remember that after 1989 most all repair is covered under warranty, I believe in using Smith themselves for all work they will do. Now, there are many things they will not do, but I want to point out that in my experience they canbe less expensive then local guys and always have the right tools and fixtures to change barrels for example.
Remember, gun repair is not like car repair, the manufactures themselves are available to us at the same or often less cost, why would one ship to anyone else.
Now , with all that said, for little things , I do often use my local guy, but , to change a barrel ? no thanks I will go with Smith , same price $60.00 !
I also often send in two or three guns at once which helps a lot with shipping expense.Just my two cents !
