This is my experience with it.

Ran 100 rounds and suffered a broken extractor. Ok, it was old....but wolf paid for a replacement along with exchanging the entire batch of ammo I had. Got everything fixed and back to the range I went. I fired less than 60 rounds and the NEW extractor broke again!
Wolf refunded extractor #3 and sent me a check for the remaining ammo.


My experience has me staying clear of this stuff. Shoot it at your own risk!
