Looking to get a 590A1 and am having trouble making up my mind on the bbl length.  Main use would be just fun at the range but would also be for the occasional late night critter around the house.  Is the extra capacity worth the added length going from 18.5 to 20?

In my opinion the barrel length is almost completely negligible.

Haven't been able to find any to handle yet but I think the 18.5 has a shorter length of pull also... wasn't sure if there would be a noticeable difference between the two or not.

Same length of pull.

I put a +1 extension on my 18.5" 590a1.

I had the 20" gun longer and it has a light/sidesaddle and I'd grab it for defensive use.

I have the 18.5 as a backup but also will be using it for hunting.

1.5" on the barrel doesn't make any difference to me...more shells in the mag does.  I went with the 20".

It is noticable. It's 1.5" of a heavy wall barrel and 1.5" of magazine tube and an extra barrel ring. The 18.5" is noticably better handling. Even with a +1 extension.

+1 on the 18.5 handling noticeably better

Considering that shotguns already have a very low capacity as is, I would argue that an extra shell in the tube is more important than an inch and a half difference in length.

If we were talking about a weapon that has a lot of ammo on tap either way, like a rifle, I'd agree that shaving 1.5" off is worthwhile to make it easier to swing around. But the difference between 7 in the tube and 8 in the tube is more important than the difference between plus or minus an inch and a half on the barrel.

IMHO

I don't even disagree. Like I posted above, if I'm grabbing a shotgun to fight with then it's my 20".

I just wanted to point out that the shorter gun is a much better handling gun.

Thanks for the help, going to go with the 20" gun.  Next question is I am looking at a couple different models online, the 51660 and 51771.  I was planning on going with the plain bead and changing it out with a tritium one.

But the one with XS ghost ring sights and speed feed stock can be found a bit cheaper.  

Never been around a shotgun with ghost ring sights... can they be easily removed if I don't like them and a bead installed?  

Is the speed feed stock a liability?

If you ever plan to shots slugs at any kind of distance, I would go with the ghost ring.  It can be done with a bead but is just not as easy.  You can ignore the rear sight if shooting pellets and speed is a concern.
The rear sight should come off very easily...should just have some screws holding it on.  My front appears to be welded on so replacement may be a bit more tricky?

Not a fan of the speed feed stock.  If it's cheaper, get it and swap for the Magpul SGA when you find that the shells like to rattle loose on the speed feed.

I prefer GRS but I also shoot a lot of slugs. If you don't than go with the bead. The front sight is soldered on. The rear sight is easily removed and you could replace the barrel.

The speedfeed stock is a personal preference thing. Not mine. I prefer hogue but they are good stocks.

I agree with both of you, I had a 20" 590A1 and sold it. One of these days I'm going to pickup an 18.5".

I have both and the 18.5" is "a lot nicer" to handle than a 20".  I put a +1 extension on mine which almost equals the capacity of a 20.

My 20 feels like a boat oar compared to the 18.5.

Right here is why you need to handle both. I much prefer the handling of the 20 inch. Besides I think it looks better. Last is not a good reason but a reason non the less.

I was given a 18.5" 590 but then traded my lefted handed son for his 20 ga 870.  Now I have 3 870s and he has 2 Mossbergs.  One thing the 20" gives you is the bayonet lug.  I like pig stickers for when I run dry.

I agree with you, better handling and a little less forward weight without the second barrel ring and bayonet lug, but if I'm going outside it's gonna be a 20" gun with lots of ammo.

Like most of the other guys, I'd prefer the 20"  It's what I had anyhow. 

I put a meprolight tritium bead on it (would probably go XS next time) Esstac cards for easy shell swapping, and a Hogue short stock set.  (plus swapping springs and whatnot)  I am curious to find out how many minishells it can hold when I get a new one.
