Just looking at the Smith website, the Combat Package appears to be $155 more than the Master job which is how much the glass bead blue job costs. So I am guessing that you get the listed Master stuff plus the bead blue which makes for the Combat job. Just a guess...
I called S&W today...The big difference is indeed the refinishing. The S&W Customer Rep did say the action jobs were slightly different but he did not sound 100% confident on it.
He also told me they will re-laser whatever was on the gun which I might or might not want...
