Well, this is my first post here but I did feel compelled to make a post.
I called S&W and explained to them I own pretty much the full line of M&P including the 15/22 rifle and that I had an issue with the sights on the 22 pistol.
To my amazement they are sending me a full set of sights front and rear free of charge! Now that's customer service.
Big thanks the Ken at S&W support for your great customer service. I couldn't be happier
