Was working fine 2 days ago. Today I load the cartidges and as I am tightening the screw all the air just blows out of both cylinders in the mag instantly. I inspect the mag and can't see anything out of the ordinary, so I get 2 more cartridges and try again. The same thing happened. I did notice though that the screw seemed to screw into the mag easier than the usual amount of effort needed. I also remember putting a drop of silicone oil on the threads a few days ago. Anybody know whats going on? Was oiling the threads a mistake?
