I grew up in California in the 60s and my late father shot trap with a low gun. He shot a German 16 gauge side by. He would have the gun down at his waist, yell pull, mount the gun, and bust the clay pigeon. Everybody else shot Winchester Model 12s, Remington 870s, and, for those who could afford them, Browning Superposed. These guns were specifically made for trap shooting. His was an upland game gun and his shooting trap with a low gun was a continuation of his bird huting. There weren't too many times he missed. The times he did was because he had the gun to his shoulder when he yelled pull. I was 13 and asked him why he was missing. He told me he was getting stares and comments from the other shooters and he was looking for the gun. I told him he should not worry about the other shooters, but shoot the way he did and break the clay pigeons. As for me, I have the gun mounted to my shoulder when I yell pull. The bottom line is, shoot the way you feel comfortable and don't let some old fart tell you otherwise.
