10mm....  of course.  Had held the 9mm in a store a couple weeks back and it felt good so ordered up this gem. Added a strikefire 2, to it and now chomping at the bit to hit the range.  Need to order a lower scope ring as currently the strikefire sits too high for my taste. 

Initial impression is I'm in love....... The bad is it feels heavier than I thought it would and it looks as if the stock should fold but does not..... Oh well, now I have to wait a couple weeks till I can shoot it

Very nice

I hope Santa Claus brings me one. Nice!

Do they make mag extension for 10mm like they do with 45?

Not yet, but kriss rep says it's in the works.  There are several sites on the web that show how the 45 one can be converted

Very sweet Drg, congrats!

I just held a Vector for the first time about a week ago. I was surprised by it's size and heft. But still very cool!
