I have one I acquired second hand about a month and half ago, HP66XX. The original owner bought it new in May 2022, he put 120 rounds through it with zero failures of any kind, I have since put another 500 FMJ & HP's 115 & 124's through it with zero failures of any kind either. So that's 620 total
I also have heard about the failures to extract in the 800 round range, so I have at least another 200 to go to see. I will say I am very pleased with the gun. If I do have a failure to extract I'll just get an upgraded extractor, replace it and keep rolling. I like it enough that if I run across one at a decent price, got this one at a very fair price, I'll most likely grab it.
