You do get a longer site radius for sure. Using GO 3f Lyman shows a 100 grain charge as having MV of 1882 fps in a 26” barrel, a 43” barrel 1978. At 100 yards 501 foot pounds compared to 461 foot pounds in the 26” barrel 92% of the energy. I like the looks of long and a 26”barrel looks like a sawed off gun to me, so is a 8% increase worth the extra weight if you can get over how ugly short guns are(sic).?
