FMFP = Frame Mounted Firing Pin referred to in the Standard Catalog of Smith & Wesson as the "floating firing pin".
Beginning in 1997 all other existing frame sizes were redesigned to accommodate CNC machining. The obvious external appearance changes are similar to those of the J frames: i.e., the removal of the cylinder stop stud, a floating firing pin and a flat face hammer). These changes were completed and in the field by August of that year.
