Herb Orre worked for Winchester in the 1930's and is credited with putting the first 21 together. He did not design it as some will have you believe. Many trap and pidgeon shooters had their guns set up to shoot the left barrel first claiming they could stay in the gun better. If you are going to shoot trap with it by all means get the one with the higher stock. I got my first yard in trap shooting with a 30" Model 21. You can do no better.
