Just finished it. This one will be the sidearm of the MK-1 Robot I am building at the moment. The Kriss K10 is brand new today so in a not too distant future ( maybe 20-30 years ) they might still be in use as older firearms are today.
It's kind of ugly but I like the very different design it has compared to other firearms.
There is a version of this one available at my shapeways shop.
