Just a quick one. My Domie appears to have a leak. It only happens when the barrel is flexed up say when you are accidentally resting it pointed end down when loading or flex it when putting it in the case or similar. It appears to be coming from the Barrel - breach joint. Fires very well and loses no air over weeks but hisses when the barrel is stressed even half a MM or so. Any ideas?
As always thankful for advice.
