I recently purchased a .22 and a .40 FS, M&P handguns. Called S&W about the possibility of ordering sights for the .22 that match the "3 dot" sights of the .40. Their response was that the front and rear sights for the .40 or 9mm will press/slide into the .22. They're sending me a free set of "3 dot" sights for a 9mm/.40 and told me that they'll fit perfectly into the .22 frame. Does this jive with the experiences of the M&P forum members?
