Ditto - 3 Kahrs here also and after well over 500 or more rounds through each, not one has seen a failure to feed, fire, extract and eject, which is a testament to how well they're built.
But I still did not trust them until I ran 200 rounds through them as the manufacturer recommends. And I won't take a brand new car on a long trip at a steady 65 mph until it has 500 miles on it at varying speeds.
I would, however, wear the hell out of a virgin, if I could find one...
