Frank,
Thanks for checking and clarifying. Additionally, I had been wondering about that 2nd trigger guard and why they didn't mention anything about the 1st one! This is a good thread. I just picked up my 1006 last weekend (after looking for one for a while) so I had recently read that section (but not the 45xx one) :P
I am impressed though -- the 1006 was definitely ahead of its time (undercut trigger guard, serrated front strap, checkered trigger guard and TIGHT). I must find a 1066 now
