I am working on my own version of this.
I was wondering about the stop pin.
It looks like it is "floating" in your pics as there are no scales to prevent it from walking out.
I have one tidbit for you and others looking at this.
the Endura (and Matriarch 2).pivot has the same diameter as the stop pin, and it's hardened. It has the "D" shape, and has a screw on both ends to hold it all together IF you have removed the scales. if not, then you have to drill the scales to fit the pin.
Just remember that the PPT has a .155-.158 width inside the liners from the pivot to the back screw.
I am almost finished with my PPT. Need the stand offs and TI clip (have to drill and tap clip holes).
I will post the mod HERE when I get it done.
I think a lot of people will be interested in this one. Like it or not, it was/is a lot of work, and I like it.
I call it the Outlander PPT.
This thread got me thinking about getting the scales off, so thank you for the inspiration.
I am not saying what mods I have done, yet, but without the clip, I am down to 3.4 OZ!
The steel liners are heavy. I can see with Ti liners, maybe .5 OZ more can be removed. And the knife would be a bit more durable, if you think SS steel isn't durable enough.
