Except for the stock and barrel length, my Kriss pistol has the same trigger, sights and related features as the carbine. I have had flawless performance with this gun for hundreds of rounds and the addition of an optical sight has allowed me to obtain sub 3" groups at 50 yards. As far as what use there is for a Kriss, I keep 3 loaded 13 round mags and one 30 round mag in my briefcase and consider the package a great traveling companion.
