    18 1/2" or 20"

    OK here is my dilemma. I have decided that a Mossberg 590A1 needs to come and live with us. I am just having a little trouble deciding between the 18 1/2" or 20" barrel lengths. This will be used for home defense. I realize that there is little difference in the way they handle. I guess it is more a question about capacity than length. So I would like some feed back from the members here. do you feel that the extra 3 rounds are a deal breaker?

    Both shotguns being equal there is only a 1 round difference between a 18 1/2 and 20 inch barrel with extended mag tubes. Do both the shotguns you are looking at have an extended mag tube?

    I like the 20" and 8 round capacity, rather than 18" and 6 rounds. Also, I had a Saiga 12ga shotgun with 10 round magazines. I found it to be very awkward to handle. I prefer the handling of the under barrel tubes.

    If you go past 6 rounds of 00 buck and slugs you really have a mess on your hands and maybe an AR is your next option. I in no way feel under gunned with 6 rounds of 12 gage.

    We have been experiencing home invasion robberies that have involved multiple perps and high order violence. If you need your shotgun, you most likely have all the ammo you're going to get, until the problem is resolved. If you are comfortable with 6, cool. I'll take 8 until the KSG which carries 15, proves itself.

    If that's the case and home invasions by crews are the concern I'd forget the shotgun and go straight to AR. 30 rounds twice with a mag clamp. 2 additional rounds MAY make the difference but 24 more sure seems better.

    Just another traveling mans opinion though.

    My HD shotgun is a 21" turkey gun with the 8 shot extension tube, screw-in choke tubes, weaponlight/laser and a fiber optic front sight. I prefer the 20/21" length to the 18"/18.5". Just my personal preference.

    It really makes no difference, but for HD I would prefer the shorter. If you can't hit the home invader with 6 rounds of buck, two more probably won't make much of a difference.OMO

    Look at your home and if you have some tight spaces you may want to go with the shorter barrel, just for that little bit of extra maneuverability.

    Six rounds of 00 buck will go a long way inside your home. Like someone else said above, you should be able to finish the job with 6 rounds through your shotgun. If you don't think you can then you need a different type of weapon.

    I just bought the 20" Mossberg 590A1 and I chose that one for increased ammo capacity. Nonetheless, I think that both are perfectly fine for their home defense role so don't read too much into it. A shotgun is a perfect home defense firearm but it is not the best firearm to clear a house due to its length. Therefore, I would just buy whatever feels best for you (length, weight, size, capacity, etc.). More importantly than length, make sure that you can handle the weight difference between both. I had no problem with the 20" Mossberg, but some people can't handle it so well. Go to your LGS, handle them both and then just get whatever feels and seems best for you. Just make sure that whichever model you get, that it has ghost ring sights and to put a light on it.

    Thanks for all the replies. I have been leaning toward the the 18 1/2" model. Doubt that I will have much cause to clear my home. Hope to stay in a good defensive position until help arrives. Of course we all know about the best layed plans. As far as needing a combat rifle, it is not practical for me were I live. Houses are to close together and a bullet will penetrate further than buckshot. Now I don't want to start a debate on that issue. Just not right for me. I will check both out before purchasing and see which fits the best. However watching the news with all the civil unrest around the world and knowing it can happen here very easily. Keeps pulling me toward those 9 rounds. Know what I mean.

    The best Mossburg to get is the new 930 SPX. It has fantastic rugged tactical sights, and has a picatinny rail if you would ever want to put a red dot sight on it. Barrel is only 18.5 inches, and it has a 7+1 capacity for a total of 8 rounds.

    They are not that expensive, if you shop around. I've seen a number of dealers on gunbroker.com selling them between $600 and $650:

    Mossberg 930 SPX 12 ga Shotgun : Semi-auto at GunBroker.com

    Mossberg 930 SPX 12 Gauge 18.5" 8 Shot Shotgun : Semi-auto at GunBroker.com


    It is more than worth spending an extra $100 to get this Mossberg over a 590A1. Recoil will be much lighter, due to the gas operated action. And you will be able to shoot faster and more accurately, without having to bother with chambering additional shells manually.









    Checkout the lack of muzzle rise in these videos. You can't shoot a 590A1 this fast:








    For a few dollars more, you can also get the gun with a pistol grip if you want:

    Your choice on whether the AR would be right for you or not, but don't think for a second that your buckshot is somehow going to penetrate less than a .223 round will. A quick google search of ".223 penetration" turned up this article immediately, and many others like it.

    Whatever you end up picking though good luck with it, a shotgun is certainly a very good choice in any event.
