Browning has no warranty. They say they'll correct POI if it is over 6" off. That's too far for turkey. Other high end O/Us are the same. It may be rare for a poorly regulated gun to make it past QC, but it does happen.
I would like a baby frame 28ga, but I'm not buying one unless I can verify POI first. Other gauges you can get Yildiz. They'll fix the problem. The baby frame 28ga Yildiz isn't imported into the US, AFAIK.
I'd call and talk to Browning. Maybe they recognize a turkey model should be held to a higher standard for regulation.
