Hmmm ..... good question. In my experience they are usually listed as "prohibited - e.g. the owner of Marstar currently has 4 of these pistols personally listed for sale (in "John's Gun Vault" on the website) as "Prohibited Pistols". My initial thought was that they are prohibited because the original 7.63mm chambering (i.e. .30 cal.) is less than .32 caliber ..... and it seems to be generally thought that any handgun chambering a centerfire cartridge of .32 caliber or less is "prohibited".
However, I have just re-checked the wording of the applicable Criminal Code provision (in Section 84) and it actually reads as follows (emphasis added):
“prohibited firearm” means
(a) a handgun that
(i) has a barrel equal to or less than 105 mm in length, or
(ii) is designed or adapted to discharge a 25 or 32 calibre cartridge,
but does not include any such handgun that is prescribed, where the handgun is for use in international sporting competitions governed by the rules of the International Shooting Union,
Clearly, this current wording does
not prohibit all centerfire handguns which are .32 caliber or less (as commonly thought) - rather, it prohibits
only handguns chambered for .25 and .32 caliber cartridges! As a
.30 caliber pistol, the Mauser Model 1896 pistol, should not be caught by this silly prohibition .....
Having said that, I suppose this model may be specifically prescribed as a prohibited firearm somewhere in the regulations .... I haven't checked. One should probably check with the firearms technicians at the CFP to see what they say. Mind you, in view of the above, if they say it is prohibited I'd want them to be specific as to why they say that - i.e. are they somehow deeming a .30 caliber handgun to be either .25 or .32 caliber .... or is there a specific mention of this model in the regulations?
(To further complicate matters, if the particular handgun in question was manufactured before the end of 1897, it is an "antique"!)
