Shotgun Mag Extensions

[Hulamaster]

OK, I think I may know the answer here but obviously I'm not sure, hence this post. I have a friend who has 12 round magazine extension for a Remington 870/1100/1157 left over from his competition days (way before current mag laws). He would like to sell it here on Calguns BUT he also wants to stay cool with Calguns and the law. So, my question is, can this extension be sold, legally, with a two round "plug" as used in bird guns? Thanks all.

Thanks for your reply! Can I get a second? Moderators ok with me putting this extension up for sale on Calgun?

Fixed or not doesn't matter.
Now, is the extension itself 12 rounds, or does it add 8 rounds to a 4 round gun? That could be the deciding factor here.

As I said understand it that is a fixed magazine tube. NOT a removable magazine so it shouldn’t matter.

CA large capacity magazine laws makes it illegal (felony) to import, make, advertise for sale, or transfer a fixed tubular magazine for a bolt-action shotgun or pump-action shotgun or semi-auto shotgun. [PC 32310(a)]
Increasing the capacity of a fixed tubular magazine to be greater than 10 rounds is considered making a large capacity magazine, which is illegal to do for a bolt-action shotgun or pump-action shotgun or semi-auto shotgun. [PC 32310(b)]

CA large capacity magazine conversion kit laws makes it illegal (misdemeanor) to make, import, or transfer magazine parts that could be used to increase the magazine capacity of a fixed tubular magazine, on a semi-auto shotgun or pump-action shotgun or bolt-action shotgun, to over 10 rounds. [PC 32311(a)]

CA DOJ measures magazine capacity on a fixed tubular magazine by using the shell length marked by the manufacturer.

Magazine extensions for fixed tubular magazines for bolt-action shotguns, pump-action shotguns, and semi-auto shotguns are CA legal; if they do not increase the capacity to be greater than 10 rounds.

Lever-action shotguns with fixed tubular magazines are exempt from the CA large capacity magazine laws. [PC 16740(c)]
^It is CA legal to (make) increase the capacity of a fixed tubular magazine on a lever-action shotgun to be greater than 10 rounds and CA legal to advertise it for sale or transfer it in CA.

Due to Federal Court actions...
If a person legally owns a large capacity magazine, then they can continue to legally possess/use it. But, they cannot legally advertise it for sale or transfer it in CA.

Therefore...

If the magazine extension for a fixed tubular magazine for a pump-action shotgun can increase the capacity to be greater than 10 rounds, then it is illegal to advertise it for sale or transfer it in CA. [PC 32311(a)]

If a pump-action shotgun has a fixed tubular magazine with a capacity of greater than 10 rounds, then it is illegal to advertise it for sale or transfer it in CA. [PC 32310(a)]
^In order for this pump-action shotgun to be CA legal tom advertise for sale and transfer in CA, the fixed tubular magazine needs to be permanently altered so that it has a capacity of less than 11 rounds. [PC 16740(a)]

So of a shotgun is labeled "2.75 or 3" shells" which one do they use?

[bugsy714]

Well we are examining the insanity of this lol how about if we use mini shells? Have you know increase the capacity of your shotgun tube

OK, thoroughly confused. To be safe, I'll take it off my "for sale" post. Don't want any trouble.

Nobody with a brain cares.
Nobody is enforcing this because nobody understands the law.
Why not just keep it that way you can keep it hidden in your garage and nobody would now the difference? You might need it someday?

3"

Per CA DOJ BOF...
The largest length of shell marked by the manufacturer is utilized.

CA DOJ BOF enforces it, the last time it (fixed tubular magazine capacity limits) came up is when they notified (12-2016) CA FFL dealers and UTAS-USA that the UTS-15 needed to be modified in order to be CA legal due to its fixed tubular magazine system being considered a large capacity magazine.

The UTAS UTS-15 has two fixed tubular magazines that automatically feeds shells from both tubular magazines in an alternating pattern. Because it automatically feeds from both fixed tubular magazines, CA DOJ BOF determined that it is one ammunition feeding device and in order to be CA legal, the tubular magazines needed to be permanently altered so that they could only hold a total of 10 rounds (5 rounds per tubular magazine).

Because the Kel-Tec KSG, S&W M&P-12, and IWI TS-12 requires their multiple fixed tubular magazines to be manually switched to feed, CA DOJ BOF determined that each tubular magazine is a separate ammunition feeding device.

Per CA DOJ BOF...
UTAS UTS-15 = 14+1 capacity = CA illegal large capacity magazine.
Kel-Tec KSG = 6+6+1 capacity = CA legal.
S&W M&P-12 = 6+6+1 capacity = CA legal.
IWI TS-12 = 4+4+4+1 capacity = CA legal.

The tube itself isn't illegal, is it? It can only hold 7 or 8 shells, but it's marketed as a 12 shot extension because that's the total capacity when installed on a particular shotgun.

If the extension can be installed on a magazine and be able to increase the ammunition capacity to be greater than 10 rounds; then it is considered a "large capacity magazine conversion kit" and illegal to make, import, advertise for sale, or transfer in CA. [PC 32311(a)]
