Bought a brand-new Tamer in .410 the other day, took it to the range the following day with a box of #6 3" shells and 2 boxes of slugs.
First issue: didn't want to lock up tight with a shell in the chamber. Several tries to get it to lock without hinging open (without pressing the release bar).
Second issue: noticed later on that it was opening on its own under recoil, again without pressing the bar. Was locked up tight, then when fired the breech would actually come open between 1/8 and 1/4".
Anyone ever see this kind of thing before? Suggestions? I'm up in Canada, service and repair seems pretty tough to get done out here.
