I like the Fabarm pumps very much, they have a very solid precision quality feel and excellent barrels. The carbon fiber model has a very high cool factor but not much in the way of sights, the parkerized one has better sights but doesn't look as sexy. I went with carbon fiber and found that it shoots 00 Buck perfectly to point of aim although it'll rock you pretty good due to it's light weight. I need to try some reduced recoil ammo in it instead of the S&B Buckshot I've been using up until now. Newer models have an extended length forearm that overlaps the sides of the receiver when pulled back, very good ergonomics and they have threaded inserts that can be used to mount an accessory rail for the HK tac light. Either one goes for around $450 in the Houston area.
It's hard to find much in the way of accessories for either model other than the factory stuff (pistol grip stock, mag extension). I'd like to put a sling on mine but haven't come up with a decent way to attach one at the mag tube end so far.
I'd buy another one in a heartbeat even though they do cost more than a Remington or Winchester. The Fulton Armory FN combat shotgun is worth a look too.
I have a Benelli Sport model shotgun that's used for clays, it's stone reliable and wouldn't trade it for anything. I'd love to have a M1 Super 90 in the safe but can't justify the 2X cost factor compared to high quality pump guns.
