The legality of Ruger 10/22 magazines that may contain more than ten rounds of .22 LR
ammunition has been ruled on by the RCMP.
Following is an excerpt from the RCMP web-site outlining its position on these
magazines as of July 27, 2016.
"The maximum capacity of a cartridge magazine is set out in Part 4 of the Regulations
Prescribing Certain Firearms and other Weapons, Components and Parts of Weapons,
Accessories, Cartridge Magazines, Ammunition and Projectiles as Prohibited,
Restricted or Non-Restricted (the Regulations) under the Criminal Code.
Pursuant to the Regulations, a magazine that has a capacity which exceeds the
maximum permitted capacity is a prohibited device.
Specifically, paragraph 3 (1)(b) of the Regulations prohibit a cartridge magazine that is
capable of containing more than 10 cartridges of the type for which the magazine was
originally designed and that is designed or manufactured for use in a semi-automatic
handgun that is commonly available in Canada.
22 Long Rifle calibre magazines designed or manufactured for 10/22 platform rifles are
also inherently designed or manufactured for 10/22 platform handguns.
Because 22 Long Rifle calibre 10/22 platform magazines are designed or manufactured
for use in a semi-automatic handgun, they are prohibited devices if they are capable of
containing more than 10 cartridges.
The 10 cartridge limit for the 10/22 platform applies irrespective of the type of firearm it
is used in."
