Re: venting mags

Sounds like the valves are freezing. As the gas decompresses, this drops the temperature rapidly. The lower the temperature that you're firing it in, the quicker this will happen. Also, the faster you fire, the quicker it happens, so full auto from a pistol on a cold day is not a good combination.

Re: venting mags

You got any mags that work? Could be a hammer issue, not releasing back to close the valve correctly.

Re: venting mags

Are these by any chance for the M9. WE mags are known for venting gas in lower temperatures. My M9 does it occasionally, and there isnt anything wrong with the mags no stickiness or dodgy seals.
