Special Bulletin for Businesses No. 73

Armi Chiappa introduced both the Model m four-22 Rifle and the Model m four-22 Pistol in late 2010.  Both firearms are semi-automatic, and chambered for 22LR rim-fire ammunition. The cartridge magazine sold with both firearms has a nominal capacity of 28 shots.  The magazines are common to both the rifle and handgun (Pistol) version of the firearm and all advertising material portrays the two firearms with the 28 shot magazine.  There is a reference in the Armi Chiappa advertising  to a ten shot magazine for jurisdictions where there are cartridge magazine capacity limitations.

The ten shot magazine for Armi Chiappa Model m four-22 which is sold as an accessory, is an unregulated item in Canada; however, the 28 shot magazine for the Armi Chiappa Model m four-22 is a prohibited device, since it exceeds the legal capacity for use in a semiautomatic handgun.  


All 22LR rim-fire calibre semi automatic handgun cartridge magazines are limited to 10 shots of the kind or type for which the cartridge magazine was designed.  Cartridge magazines are not serial numbered. The cartridge magazines in question are "designed and manufactured for use in a handgun," and therefore fall into the following legal class:

  1. The ten shot (10 shot) cartridge magazine is an acceptable cartridge magazine.
  2. The twenty-eight shot (28 Shot) cartridge magazine is a "prohibited device" and unlicensed possession is an offence.
