Be careful some of those "matte stainless" finish isn't stainless but paint. Especially if the part is aluminum.
My beretta m9 compact inox is stainless barrel and slide but has a coating over the stainless and the aluminum lower is painted to match.
I would contact taurus first with your exact model and serial and ask them if it will hurt the gun to do light polishing.
