Hello Mr. Rawles,
This information may be useful for Americans living in states with strict magazine capacities.
A loophole exists under Canadian laws that allows shooters the ability to legally bypass magazine capacity restrictions.
Under Canadian law, a magazine DESIGNED for a rifle may only hold five rounds of the caliber it is designed for. A magazine designed for a pistol may only hold 10 rounds of the caliber for the pistol it is designed for. But there is no law prohibiting the use of a pistol magazine in a rifle, a magazine designed for a different caliber than the caliber of gun it is being used in, or loading different caliber ammunition in a magazine than what it was designed for.
This loophole has been exploited in the past as follows:
– Using .40 caliber pistol magazines to hold 13 founds of 9mm
– Using 10 round .223 AR-15 pistol magazines in an AR-15 rifle
– Using 10 round 7.62×39 AR-15 pistol magazines in an AR-15 rifle, holding 12 rounds of .223
A new development is unfolding now, where 5 round .50 caliber AR-15 rifle magazines, capable of holding 15 rounds of .223 are hitting the market.
It is not inconceivable that in the near future, 10 round, .50 caliber AR-15 pistol magazines will be available which under Canadian law will be legal and will be capable of holding 30 rounds of .223 – completely bypassing the the rifle magazine capacity restrictions.
Here is an article on the subject.
And here is a Canadian business that is 5 round .50 caliber magazines.
