I think I found a set screw that I can use for the front site. Will try to get some site time in between rain showers over the next few days.
Btw: Ed, I think I found, well I did find one of the 6mm set screws for the transfer port mod. Looking at it though, I do not think I can open it up more than .140" diameter. The minor diameter of the threads will break through. I'm sending a pm now.
