Congrats on the snub! Great thing about a revolver is they go BANG" every time you pull the trigger. In over 37 years I have never had a FTF / FTE issue with any of my S&W's. Cannot say the same of my semi's.
Try Keltykes advice. The trigger WILL improve dramatically with a set of Wolffs' in it. Very cheap improvement that will definately improve your accuracy. Mr. Wolff knows his springs!!!! They are the only ones I will use in any of my handguns.
