Tim, I just went through the FAQs (again) on this, and it seems to be just a dodge by H&R to avoid liabliity. I personally wouldn't hesitate to put a high pressure barrel on one of these frames, shooting factory or less loads. I wouldn't hotrod anything. Do you think I'd be at risk?
An adder: I would think if there was anything seriously wrong with any of these frames they would have been recalled.
