I don't think the mag seals are the problem. At the moment I don't have another mag... but if the seals were a problem I'd be able to hear a hiss wouldn't I? It could be a valve knocker problem... although I have no idea how a valve knocker could go wrong. Without the mag in, I peered into the mag housing to see if the valve knocker was doing what its supposed to do and it was. Racking the slide would pull the trigger back, and pulling the trigger would make it move forward. And it should hit hard, because I have an upgraded recoil spring in there.
The ultimate measure of a man is not where he stands
in moments of comfort and convenience, but where he
stands at times of challenge and controversy.
