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!
