I had an early KP1, my serial number was double digit, and it gave me fits. When it went bang, it did it well but it did not always go bang. Knight was always speedy and helpful when I had problems but I quickly got fed up. I live in Louisiana and we can use the 45-70 for primitive arms season and I had to pull out the handi twice to hunt. I realized that I never should have put the handi down and actually bought a couple more when Knight refunded my money. My advice would be to either wait until the new trigger group is released or go with a Handi. The reality is that my standard handi 45-70 out shoot the knight anyway. I now have a ultra 45-70 and a standard 444 as well but I have not shot either yet. Hopefully they will shoot as good as my origional handi.
