Important discovery!!!!! Last night I was cleaning up the basement and noticed something about the Sig Somethin Extra kits. One of the boxes has the weight listed at 4.25 - 4.75 lbs as I have previously stated in the thread. However, another kit that I looked at has it listed as 4.25 - 5 lbs. This claim seems to be more in line with the results we seem to get. I have been commenting on this subject and feel that I needed to post this find. The"5lb" box is all violet cardboard. The "4.75" box is white cardboard with a violet sticker(s). Don't know which box is latest revision or anything but assume the newer one has a more accurate description.
