I have a serial number that's pretty close to yours (EAA19##). If my very recent experience is any indicator, what you're likely to get back is your same frame (which is inside the plastic housing), a new takedown pin, and possibly one or two other new parts. With mine, I received a new takedown pin, a new plastic housing, and a new slide, but I think the latter two (the housing and the slide) were replaced because I requested it, not because it was necessary to fix the problem. You're likely to find that getting the new takedown pin out of the frame is a real bear. But, try rotating it a full 180 degrees counter clockwise, instead of 90 degrees counterclockwise, and it should come right out.
I've been back to the range once since this last trip to S&W, and I had no problems through 200 rounds. Once I get another 200 rounds downrange (hopefully tomorrow), I'll feel more confident about the pistol.
