Well I shot 4 magazines thru my 15-22 pistol. Absolutely no issues, no failures of any kind. This gun will fire as fast as you can pull the trigger, a blast to shoot. Shoots directly to the point of aim, not front heavy, all controls crisp and clean operating. OD'd the grip and one mag, I have rail covers coming, will shorten and OD them when they arrive. I'd purchase this gun again.
