To eliminate any confusion here are pictures of what I am speaking of. I have worn the internet out and have not found another slide stop that looks exactly like the new one I received. It has some extra beef in the area of the shaft and a step milled into the middle of the outside of the stop. I have provided the part number and pictures below.
Here are both the OEM and new slide stops. The one on the right is the new extended version with the nub already profiled to work in the 97B.

Photobucket has become such a pain in the butt this stuff now takes forever. I hope this helps anyone else looking to upgrade their slide stop, it sure makes life easier for me plus it looks great too.
