I need quick info on the original cleaning/tool set for the 3 inch round butt 547 9mm and the 4 inch square butt: What is included in each? What are the differences between the 3" set and the 4" set? How are they packaged ? I have seen "standard S&W 4 inch cleaning sets" on line with the rod, brush, pad and screwdriver packaged in a clear 'plastic'-type bag . Are these one-in-the-same as those that came with the 547's? Thank you, Steve (sck547 Oct 7 2012)
