Is the frame for the standard M&P 9 the same frame as the M&P C.O.R.E. 5" ? In other words could I take the slide off a 5" M&P CORE and put in on a standard M&P full size frame? Both pistols are less than a year old. I want to know because I have an M&P with a trigger job and want to put my 5" CORE slide on it. Thanks.
