The original problems were over exaggerated through the internet being retold by those that only heard of the problems with no first hand experience. I did receive a new (updated) barrel from Keltec with a different twist although I had no issues with the original barrel.
Keltec makes some interesting firearms but match grade they are not.
Accuracy is decent but not great. I have a Burris FF on mine which works very well with the PMR30.
