So in response to your claim that you own a factory 9-shot 18.5" Mariner, I'll have to politely say B.S. You wanna show me I'm wrong then post us a picture of your actual shotgun instead of pointing us to misprinted data on the web. And back to my initial point in all of this, you can't increase magazine capacity by simply changing the magazine tube on a Mossberg without also changing the barrel. Use the search feature on this forum and you'll find that the question of increasing a Mossberg's magazine capacity has been discussed ad-nauseam. The only way to do it is to also replace the barrel, which is what I've been saying from the onset. In the mean time, I'll look forward to seeing those pics of your 9 shot 18.5" Mariner. |

Mossberg 930 SPX, 18.5 barrel
7+1 capacity, 6+1 if using Federal LE132-00 unless you change the mag spring. Given that most magazine tubes tend to start right about where the chamber of the barrel starts and; Given that most 2 3/4 inch shells are around 2 1/4 and 2 3/8" unfired (sorry, SCSOV509 but the 2 3/4th inch is for the fired shell.) 7*2.250 = 15.750 inches 7*2.375 = 16.625 inches Both easily possible with a 18" long mag tube However...... 8*2.250 = 18 inches...where does the spring compress to? 9*2.250 = 20.25 inches...not really enough length in an 18-inch long tube for 20+ inches of shells is there? SCSOV509 is absolutely correct that more than seven 2 3/4-inch shells won't fit in an 18-inch tube. (Well not with any currently produced receivers that I know of, anyway.)

"Magazine capacity
The Model 500 comes in a variety of different receiver configurations, whose main difference is the magazine configuration. The basic Model 500 comes with a magazine tube capable of holding five 2 3/4" shells, which is called a six shot model (a full magazine plus a round in the chamber). The 500 is also available with an extended magazine tube that holds seven rounds, making an eight shot model. The 590A1 is available with five and eight shot magazines, sold as six and nine shot models respectively. The variants with the extended magazine tubes use different barrels, as the barrel is held in place by attaching at the end of the magazine tube. The shortest barrel length available for the eight and nine shot models is 20 inches (51cm), which fits flush with the long magazine tube. A ribbed 28 inch (71cm) modified choke field barrel was also manufactured for the 8 shot model 500. The shortest barrel for Title I six-shot models is 18.5 inches, while military and law enforcement personnel (as well private persons in NFA states) can also get a 14 inch barrel (the 590 Compact), which is flush with the six shot model's magazine. http://en.wikipedia.org/wiki/Mossberg_500 Anyway , the choice for me is the 7+1 - 18" Remington 870 or the 6+1 - 18.5 Mossberg 500 1 shell difference .. safety placement ... price |

My 500A came with a pistol grip, 30 in over all length, I think it's an 18 1/2 in barrel. Holds 7+1, added a side folding stock to it. Don't know if i really like the stock, it looks badass, but it has a bit of wobble to it when it's extended.
7+1 Stock folded And, no, I'm not BSing, it really is mine. Think there's a deal to get the stock and a pistol grip, swap em out however you want. Last edited by ah64mech13; February 24, 2009 at 12:58 AM. Reason: Forgot something. |

Oh yeah... Forgot about their handy little chart. I just know it, and my dogs are both mutts and do everything I ask. The guns have an easier time, they just have to go boom when i tell them, and they can't pee on the carpet..

ah64mech13, I'd agree that your shotty does appear to be a 20" gun, although there is no question that you can physically fit 7+1 in an 18.5" of the right length. My whole point again is that you cannot increase a Mossberg's capacity by simply switching tubes or adding an extension as some have suggested. A Mossberg magazine tube change is going to require a barrel change as well, which is why I suggested an 870 if you want to add an extension. Quote:

I have a saying that I should adhere to.
Never argue with an idiot, they will drag you down to their level. Then beat you with experience! We have a sign on the door of my shop, "There is no such thing as CANT, so if you cant do it you cant work here" Ive seen Mag tubes on Mossbergs that extend well beyond the barrel, not that Id do it but anything is possible. PS scsov509 your math skills are remarkable |

Vince... Not on a 500 you haven't... unless they have a cantilever lug... the barrel is held to the receiver only by a 5/16th or so retaining bolt... Barrel must have a lug and air is not a suitable mounting surface for said lug... on any other model of mossberg it may or may not have a female barrel retainer nut like the rem 870 which allows a separate tube extender but the tube still must be shorter than the barrel...
Mossberg has a website now-a-days for those who wish to debate further, with me, the mossberg offerings... Short of a single shot junker or 2 I have never looked at or owned any other make. Brent |

The top gun is only a 500 receiver, the magtube is not a 500 mag tube or is an aftermarket offering which in essence is a 590 mag tube and barrel.... the second gun is far longer than 18.5 inch barrel also not a 500 barrel or tube.
