FYI, I did speak w/ support @ S&W today & they did state that if you apply this mod so that the tube insert does NOT contact the foil switch, it will NOT void the warranty.

I was dismayed that they were not interested in taking down the dimensions for them, or Insight to hand out the tubes for fixing the issue but at least it can be fixed. He said that this is an Insight issue so S&W stays hands off w/ it. That is kind of a ****** position to take as we purchased it from them, they need to stand behind the product, not play virtual hot potato w/ us. Erggggg!
