I think people aren't pushing the magazine far enough in and are trying to guess roughly where the magazine is SPOSED to sit. When the magazine is seated correctly, a small portion overhangs the left side of the breech. I found myself cutting the fronts of polymags when I tried to wiggle the magazine in so the probe would enter the little round pellet cut out. I started pushing the magazine all the way in until the magazine cut out and the breech load area were flush and no futher problems. With either of the two supplied magazines. Now if someone could tell me which Hatsan has the metal magazines that are the spitting image of these...
