Hi All,

I've got my Mossberg 390 tactical and i've got my S&J +2 mag tube extension.

Obviously I want the mag capacity limited to 5 rounds of 3" shells (6 x 2.75")

How has everyone else gone about blocking up the tube so that it feeds reliably and still accepts the maximum legal number of shells?

Would love to hear all the details!

Cheers guys!
 
Forgive my (likely) ignorance, but I thought that there was no limit on magazine capacity for a pump action shotgun.

I find my self in the same situation, i assumed that the tube when installed would only take 6 X2 3/4 and 5x 3 but was i wrong.

These should have a limiting device installed when sold, otherwise i dont understand how its legal to sell these +2 for the 930 as its a semi.

This thread might help you
 
Ahh drat, I didn't see this thread until now :)

If your shotgun is chambered for 3" and 2 3/4", they take the largest shell and go by that.

In this case, so long as you cannot fit more than 5x 3" shells, you are fine.

am I wrong in assuming if it were marked for a mossberg 500, why should this play out any different than the ruling of LAR15 mags in AR15s.

If you can find a 12g handgun with a mag extentsion, that also just so happens to fit a Mossberg 930, then yes, this would apply.

Meaning more that if an extension that was designed for a pump shotgun, and is labeled as such, why would it be illegal for it to be placed onto a semi-automatic shotgun. I'm just playing with the law's logic here. Folks load .40S&W mags with 9mm for their glocks, others use 10 round LAR mags in their ARs, I'm just curious why a mag-tube meant for a pump action can't be used on a semi.

Magazine capacity is determined by what the magazine is designed to fit and what the magazine is designed to hold. The reason people can stuff 9mm into a .40 magazine and squeeze out and extra 3-4 rounds is that the magazine is designed to fit a handgun and is designed to hold .40 S&W rounds, and is limited to hold ten .40 S&W rounds. It does not matter how many rounds of another caliber it can hold as long as it can only hold 10 rounds of .40 S&W.

LAR magazines are handgun magazines. They can be used anywhere they fit. Remember the laws are based on what it is designed for, not what it is used in.

As far as the shotgun goes, I don't know where to start. Technically an extension is not a magazine, however I do not believe there are any shotguns in Canada that are classified as pistols, and even if they were, none are long enough to warrant an extension, and none have a box magazine of over (or even near) 10 rounds. It doesn't make sense, but that's juts the way it is.

What if barrel makers were to label a barrel for 3.5" it would allow more 2.75" no?

Correct. But unless it can actually fire that size the barrel maker will get sued good!

For 3" you make it so you can fit 5.9x 3" shells. Which I believe is 6 rounds. Then 1 in the chamber and 1 ghost loaded gets you 8 shots total.

Does this mean chambered for 3.5 or the gun needs to be naturally made in a 3.5 variation at some point?
 
Chambered in. All semiautomatic shotguns are limited to 5 rounds in the magazine, of the largest cartridge said shotgun is able to fire. This is akin to loading 38 SPL into a tube fed semiautomatic chambered for 357 Mag. The limit is imposed on the largest cartridge the rifle is built to fire.
