I find only a couple of 12ga Styles in their current Gun Library inventory.
I field tested a Traditions 16ga several years back. I don't recall whether it was made on a 12ga frame, but it felt like it. Sub-6# 20ga surprises me, but maybe.
Thanks again for another reply. It doesn't look like this was a very popular gun and I haven't been able to find anyone that owns one. I talked to a guy a Fausti USA and he verified the 5.75 weight, and said the ST would not weigh any 6.5 lbs; that it was lighter than that. He said the gun was as good as any of the others they produce, but lacked the engraving and finish of their higher priced guns. He said they wouldn't honor the warranty, but would be willing to fix any problem on my dime. I'd probably just let my gunsmith fix it if I had a problem.
I'm still trying to decide if I want to risk it. If it won't shoot the heavy loads to POA, then I'd just have a very nice $800 bird gun, which I'm trying to convince myself would not be a bad thing at all.
