Had the trigger fail in my Invicius 5 and sent it back for warranty. CG was very attentive but their gunsmith proved to be not so hot. First he put a whole new trigger in saying that it would solve my skeet tube problems. It DID NOT and I sent it back, his second cure was to reduce pull and then he tested it with a "3 inch 410 and all was good". The tubes are for 2.5 410's so I am sure his proof test provided enough recoil to set the trigger. It does not set the second trigger roughly 25% of the time with 410's and I am not sure what trigger pull has to do with setting the trigger. I will be traveling the 3 hours to see Philip shortly.
