New 1720T

Shoots great, but leaks down to almost empty in 8 to 10 hours. Can't find a leak externally so assume it must be the valve. Can mis adjusting the hammer tension and the stroke lenght put pressure on the valve pin when the gun is uncocked cause a leak down?

The other thing is a pretty good blast of air coming from the frame when fired. Abnormal or air escaping from the shroud.

Mine was the same way...

With leaking down and I also have noticed some air blast from under the breech. The leaking over night was from around the gauge and it leaked from day one. I have since tried 3 new gauges before I found one that did not leak( for now ). I have also noticed a great deal of oil from my new gun coming from around the breech when shooting and also noticed this coming from the gauge area when replacing. I think the oil does something to breaking down sealant tape and causes gun to leak. Just my thoughts. It is a very accurate pistol and I hope mine is fixed!

Chris had a good response, 7 times of 10 when they leak air it's from the gauge. Take is one way to go, however, if you use the white sealant paste and let it dry over night, it is impervious to small amounts of oil and won't break down like the tape.
