I hunt with an Affinity 3, 26" barrel. I also hunt with a Remington 870 21" barrel. For ease of carry, the 21" is better, but when I sit with my gun laying down my legs, the 26" is better. I think 24" barrel would be the cats meow. Franchi makes a 24" barrel for the Affinity.. if you can find one. Good luck,
Randy
