Here is a quick snap of the invoice. BT was not factory original. I don't currently have a nsst but my thought is the recoil block prevents firing the second barrel from the involuntary second pull. I have Harry's patent and disposition (law suit deal) on that trigger and he talks a lot about the 'involuntary second pull'.
