The Armed Forces Journal summarized the Kriss this way:
This certainly wins the ?gee whiz? category for a full-auto weapon, particularly a .45 cal. The big win is in the lack of recoil. ?the pragmatic question is: ?What will it be used for?? With its small magazine size, this is a weapon in need of a very innovative magazine solution. ? It shows promise, but creates the interesting situation where the innovation can?t stop at the receiver, but must go to the whole weapon ? from ammo to sights."
