Not sure where you have your information or experience from, but I own two and they don't bobble or hiccup. I have about 1500 9mm rounds through them, combined (suppressed and unsuppressed). I wanted to verify, so I checked all the torture tests and the reviews and they are overwhelmingly positive. The first iteration (Gen 1) had some issues, but the Gen 2 is quite refined and successful. The 9mm out of the Kel Tec carbine has been used at 440yds and still penetrated a 3/4" sheet of plywood. Comsidering special forces have been using 9mm carbines (HK MP5) in combat operations for decades, I believe they are still valid in combat, particularly in our modern urban warfare settings. With suppressors, the 147gr is extremely quiet and very effective. The velocity increase from a carbine length increases the ballistics by a significant margin.
