When you pull the slide off it will really remind you that Walther built it because it is like looking at a PPK.
The only thing I do not like is they all have thumb safeties and mag safeties. My other M&P's do not have these.
I have not seen a way to defeat the mag safety and I have been looking a lot. If anyone would find a way to defeat the MAG safety on an M&P22 pistol please post.
