Why do you want a thumb safety on an M&P?
I have the same question as don. Why do you want to install a thumb safety on this pistol. It will not make the pistol any more safe. I have the same pistol and the three safeties on it i.e. magazine safety, trigger safety and the battery safety all work very well. ???
the battery safety is by far the best.
I guess Im more comfortable with the thumb safety because Im more accustomed to it Ill leave the pistol alone for now
