Matrix Precision 1911 Rail Cutting Jig - Amazing!

In this video I show how awesome the Matrix Precision jig is. This was gen 1, and the jigs have improved since, so if you are considering a jig to finish some 1911 or Sig frames, this is a way to go. Matrix also has a lot of other useful tools and jigs.
Sorry if I say YouTube in the video. This was originally uploaded to YT before YT became what it is today.
