Thought I'd add my thoughts on this gun, as I've shot both this one, and the real M&P. Real one:
I do have to say I kinda hate the real one. My first one locked up after every single shot. It was replaced with another one that functioned good. It had the thumb safety however. Unlike the Hi-Power Mk.III, where it locks the slide, with the M&P it locks the pin. This can be very confusing when you are shooting. The gun blocks, you do a standard tap/rack, and still no dice. Then you notice the thumb safety is slightly on. It is VERY easy to move. Best way to shoot the real one is with you
