I love the 21" BBl on my 11-87 SP... With Star Dot front and rear fiber optic sights I've never had any problem getting on target as far as I want to shoot a turkey, which is about 45 yards max.. It sure does carry and handle nice, and I've even used it for wingshooting a few times.. I made a triple on mallards with it once and another time killed 4 geese with 5 shots... NO I didn't leave my plug at home...

.... I dumped my 3 shots and got 2 geese, then killed 2 more before the flock got out of range by throwing single shells into the breech and firing..
Years ago before they even made any specialized turkey guns, I used a Browning A-5 with a 32" BBL... I'm only a smidgen taller than Adrian, and the barrel towered over my head with the gun slung..I was always hitting branches with the barrel...When I set up I had to be careful that there were no saplings around that the barrel might hit... It was a good gun and I killed my share of birds with it, but I like the short barrel on my current gun much better..
