32" guns are the latest fad. The longer sighting plane is a silly point. If you are looking right down the barrels, like you are supposed to be doing, you can not tell if the gun has 26", 28", 30" or 32" barrels. Your face is the rear point and the front bead is the front point and all the rib in the world should be just a very thin, flat space between the two. I do not look down a rib and see six inches of space at a angle. It is a very thin flat area so how long a barrels is not a big deal.
They, 32 barrels, are heavy barrels that are slow to get started but also very easy to keep swinging once you get them going. All the clay target games they are used in either are shot with a sustained lead or shooters do better with a gun that follows though naturally because of heavy barrels that smooth out their swing. The extra weight also help absorb the heavy recoil that the clay target games have with maybe a hundred shells shot in an hour.
Just as the 25" barrels were a marketing ploy years ago to sell more new guns this craze of 32" barrels is just another marketing ploy to sell guns. Face it no company made money unless they could either create demand or fill demand for new guns. All the big names are shooting these longer barrels so every average Joe wants one also. I
I remember years ago Remington gave a all American one of their 3200s and paid him to shoot if for the year. He did and sales went up for several years. That same shooter could have used any gun and did use another companies gun the next year. They made him a better offer, free gun, shells and a little cash. He now uses a 32" barrel and I understand he is looking at a 34" barrel for next year.
