It is worth remembering that the idea of shooting wadcutters for defensive loads is nothing new. Years ago Peters marketed a .38 special Service Wadcutter load with a 158 grain bullet at 850 fps. I have seen pictures of boxes and ammo. McGivern makes a very brief reference to them in his book.

I also have scans of an old S&W add for the 2" M&P in .38 spl from the 20s or 30s that discussed the use of the Mid Range Wadcutter as an option when you wanted a lighter load because "the sharp shouldered design of this wad cutter makes it an extraordinarily effective man-stopper at short ranges" and "the design of the bullet acts to reduce ... the possibility of the bullet ricocheting and injuring bystanders".
