I intend to. I think I'll go with 10, and I'll make sure to get those DIY kits where you buy a magazine and pin it yourself down to the legal limit. I solemnly swear I will comply with the law.
While I see you are trying to be humorous you should be aware of the law and it sounds like you may be refering to California.
The law for magazines itself is one thing, with its own punishments.
However the law for magazines used in a gun with a 'bullet button' have bigger penalties because under CA law those are guns with legally a fixed magazine. The definition of an illegal 'assault weapon' includes any centerfire firearm with a magazine of over 10 rounds.
Violation of this statute is punishable the same under state law as having an illegal machinegun is.
10 years in prison for possession. (Possibly another 10 for manufacture?)
If I recall.
While having the same illegal magazine over 10 rounds in a gun with legally what is a 'detachable magazine' on gun without prohibited features is a lesser crime. These would be guns without a pistol grip (and other listed features.)
Now there is plenty of people with illegal assault weapons. In fact most were not registered when there was the brief window to register them.
I may even support thier defiance.
However if they were to defend themselves or thier home with such a firearm then they may be going to prison after that good shoot for illegal possession.
The same would happen if you made your own by inserting a 10+ magazine in a bullet button firearm, creating a firearm with a 'fixed' magazine over 10 rounds and an illegal assault weapon.
While removing the bullet button without making it featureless would also be creating an illegal assault weapon as well.
So the penalties in many firearms for using a magazine over 10 rounds are not the penalties for illegal possession of a magazine over 10 rounds, but the much more severe penalties of illegal possession of an assault weapon, punishable by the same prison time as having a machinegun under state law.
