I love my Sport. If I had to do it all over again it's what I'd buy. I've put a 3-9x scope on it. So far that's all I've done to it. Will likely buy a new trigger for it in the next few months.

If it's only a range gun (i.e. no running around in dirt and sand and water) the dust cover / FA should be a complete non-issue. (If you're looking for utility - as opposed to looks or having an AR like most all others look.) One time out of about 1,500 rounds did it not go BANG when I pulled the trigger - and that was because I was shooting reloads and the primer wasn't fully seated.

It's an awesome gun. S&W really understood their target market on this one IMHO and totally nailed the product definition and price point.
