Well ,my colleagues, I have an exactly similar gun in my "maybe one day" to do box. Unfortunately the subject gun has conventional replacement barrels so the original ejector system will not work.My gun, very similar if not identical has thew weirdest ejector system i've ever seen
.Basically the gun ejects every time the barrels open, however the extractor legs are restricted from ejecting unless the lock has been fired, in which case a protrusion from the A&D tumbler releases the stop and allows full ejection. I'm not going to expect anyone to understand this from my description so tomorrow when i'm doe with chores I'll take photos. send them to Ted S. and we'll share with you all.
