    It’s the suppressor. Since most semi-auto pistols relies on the recoil from firing to cycle, adding a suppressor can mess up the cycling without a Nielsen device.

    There are plenty of examples of unsuppressed pistols with 3d printed frames working just fine on yt

      Seconded, this is the best explanation here. The browning action, on which most semi automatic pistol operate on, does not function well when a suppressor is added w/ out a Nielson device or ‘booster’.

      The design is made assuming the barrel weighs ____ oz, if suddenly it weighs more then the reliability is impaired.
