I have a brand new Super Nova 12 Gauge that I just cleaned for the second time after shooting 50 rounds of trap. After brushing and swabbing the barrel with the action open, I went to cycle the action but the pump/slide got firmly stuck in the open bolt position. I was able to release it only by removing the trigger assembly. Has anyone else experienced this problem? It is possible I hit the bolt face with my cleaning rod and somehow caused it to jam open? I'd like to avoid it again for field cleaning, so I'm looking for insight on what may have caused it. Thanks.
