The next generation KRISS submachine gun, the KRISS K10, was on display at the FDS Nordic Stockholm defense expo in FDS Nordic Stockholm. The finish of this gun suggests it is the final production model, not the much photographed prototype. The company said they were planning on doing the official unveiling in the USA next year.
There are a number improvements over the original KRISS Vector. The most significant change is a more compact design with a forward accessory rail and improved stock. The upper receiver can be used with both a 9mm or .45 ACP lower. Unlike the original which had four pins securing the upper and lower, the K10 only has a single pin.
