This is actually my third barrel for this shotgun. The 28" that came on it, the 18.5" cylinder, and now the 20".
I guess the money thing isn't that big an issue. It just would have bugged the crap out of me knowing that I paid $155 + shipping for a barrel that is listed for $127 just because Mossberg can't / won't keep their dealers stocked with this particular item.
I really like the compact-ness of the short barrels, but the versatility is terribly lacking with a cylinder bore. I realize this is fine for many, since the short barrels are usually for home defense. I was satisfied with mine in this role for a number of years. I just want to add some versatility to this compact, powerful package. That means adding some sort of choke option so that it will pattern buckshot further for outside-the-home use if need be (civil crisis, SHTF stuff), pattern game loads well enough to cleanly take a rabbit or squirrel, pattern tightly with the X-full chokes I have and handle well in a turkey blind, while retaining the ability to shoot slugs.
It is my hope that the 20" accu-choke barrel will do all of the above, making this shotgun a very light, handy, compact, powerful, and extremely versatile package. An (almost) all-in-one gun with just a change of choke or ammunition.
I have other guns for other stuff, so why the desire for an all-in-one gun? I dunno, I just like the versatility!
