Hi Richard,
I would not argue that point, though I owned an old RJ tool along with a holster which went wth my old R9. I can take down and reassemble the R9 without any tools as I can with many of my firearms. To me I like to bring things back to be very similar to what I owned before, the R9 with CF grips and a serial number within the same range of what I had prior, which is what took me awhile to get another.
Your tool sounds like a great piece to treasure, so I would not lend it out either, I figure there might be someone out there with an extra that they can spare and if there is not then I guess I will decide after that. I plan on doing these by hand so that is why I would rather have a model then just numbers.
Gary
