Sig MPX Pistol & Carbine Mag Capacities

If Im not mistaken, certain individuals can have Prohibited Device Licenses and can lawfully use unpinned mags at the ranges. so not everyone is equal and not assume they are breaking the law.

No such thing as a prohibited device license for individuals. Businesses yes, individuals no.

And DrXenon, the frt is only slightly more official than CGN. It is the RCMPs opinion, not the law.

You will not that the RCMP dont explain WHY they think its limited to five rounds. They simply state that is. They fail to mention that this limit is based on the presumption that the MPX is a rifle and They seem to omit the possibility that any MPX could ever be considered a pistol, which is clearly false.

You will also note they fail to mention their BS dual use doctrine.

To the OP, if you can eadily unpin a 5 rd mag and repin it to 10, then the mag was never legally pinned in the first place. Fortunately the RCMP seem to not really be bothered with enforcing the magazine nonsense that much.
 
Magazine capacity laws really are ridiculous. Why on earth would a criminal leave the rivets in the magazines of their illegally obtained firearms? The capacity laws are nothing more than sour grapes pushed at us by various past governments that can't fulfill their more elaborate firearms prohibition desires.

I said only that you would be playing with fire to possess a 10 round mag for an MPX. It is a fact that the MPX is a rifle, and it is so because Sig homologated it that way. That may change for the 8" version, but for now you need to get used to 5 round mags.

The MPX may be a rifle from the factory, but I can modify myself to meet the definition of a pistol. All I need to do then is convince the judge that this is a pistol that is commonly available and poof, 10 rd mags.

In the past, a single firearm being available amd legal to sell has fit that definition.

And then I remembered that Sig already makes and sells a pistol variant of the MPX. Whether the RCMP recognize that and make an FRT is totally irrelevant.

I'm going to go with, it's a lot simpler to follow the RCMP labs interpretation or opinion of the law than it is to push it and unpin your magazines just because the registration says pistol or the rifle has a short barrel and it's convenient for it to be called pistol in this instance just for 5 more rounds.
If the magazine is not stamped pistol I would not want to be caught with it if it could hold more than 5 rounds.
It's unfortunate these companies don't make their PCC's magazines cross compatible with one of their pistols. I went the easy route with a Kriss Vector, not as nice of a firearm as the MPX but factory non restricted and Glock pistol mag compatible is a winner for me.


So you're trying to say that if a magazine is pinned with a rivet that can be drilled out it is not pinned legally?
There is no legal way to block a magazine then. I can remove any rivet or mag body dimple with any range of tools easily purchased at the local hardware store. The RCMP know the rivets are easy to remove, they do enforce the magazine limits but they realize there needs to be intent to remove them and a person has to knowingly break the law to remove the limiter and use the magazine illegally. Who other than a criminal would do that? None of us, that's for sure.

I know when the guys from Black Leaf built their BL9's that was one thing they were really pushing on, their BL9 is registered on the FRT as a handgun, so you can legally run 10 round Glock mags in them. But should the registry ever change they would never be legally allowed to re-register as NR regardless of barrel length.

With the BL9 it does not need to be registered as a pistol, the FRT can say non restricted rifle and if it takes Glock 17 magazines you can legally use them any time unless you are hunting with it, then you must limit a magazine to your local centerfire rifle hunting limit and use an appropriate expanding projectile.
