Kenjs1,
I've got one, I just haven't had the chance to take it out in the real world and give it a comparison to an older Leica that I have. Hopefully, I'll get to do that this weekend.
There's a Sig Kilo 850 thread that has a link to a sight were a few guys have tried it out.
Main negative is it's only 4x vs 6 or more for others.
The one test I've done is to range down the alley to a known distance (103 yards). Nails it every time whether first light or high noon.
