Also- the mag says 8 rounds..it will hold nine tho. Do the mags marked as nine rounders stick out from the bottom of frame, or are they flush?
I do believe they are flush. one of the big changes from the three digit (439, 539, 639) to next generation four digits such as yours was the grips. the original 39 and the three digits had grips held in place with traditional grip screws, two one each side.

As you can see, the 3904 has snap on, one piece grips. They would fit flush with your grips, look a little odd with a 639.
