They would let you finish. If the screwed up gun could not go through chrono you would get all minor hits.I don't like it when anybody has an off day shooting. That said, the knowledge that even the big kids have one of those days now and then does bring some comfort for we legions of crappy shooters. Thank you.
Off topic & I could start a new thread, but why do it for just one question when one of these guys will know and another will get to write "go read the rulebook" (phrased appropriately to chastise and demonstrate righteousness)?
Anyway. If you entered the single stack nationals & your 45 screwed up, would they let you finish with your 9mm (1911 of course) & just score everything minor? Would like to shoot one of these matches before I reach the age where cinnamon in my oatmeal is exciting, too darn cheap to buy a spare gun for 1 match though.
