I think I may have just been really unlucky with mine but I think about the only thing it did right was go bang when you pulled the trigger. I fed it some CCi semi auto and some hollow point winchesters and it generally cycles well enough, I think a few of the issues came from the 597 mags, but the bolt/receiver pin was super loose to begin with. It would walk all the way out after a few rounds. Not to mention it was keyholing at about 25m. I liked the look and feel of it, it felt sturdy, and maybe once I get it back from warranty I’ll change my tune but as it stands not my favourite purchase
