If you want to have work done on it don't send it back to S&W, there are several good gunsmiths mentioned on the bulleye.net forum that do wonders for model 41's. If yours is still acting up after a 1000 rounds there could be several things going on. You might try polishing the chamber, if that does not work I would send it to somebody like KC custom, Clark or one of the others mentioned on the bulleye forum. It is frustrating that a pistol that costs over a 1000 dollars out the door does not run perfectly but one of those gun smiths mentioned will work wonders on yours.
