Remember something. When Mag-Pul announced this, their products were selling faster than they could make them. Faster than any time in their history. P-Mags were out of stock just about everywhere. The places that had them were selling them for scalpers prices. Assault Weapons Ban fear was everywhere, as state after state announced new gun control measures, most of which included magazine capacity limitations. The fact is IF they are going to move, they're not going to do it at a time when business has never been better. It would be plain stupid to do so. Too much profit would be lost.
Now supply is quickly catching up with demand. I'm seeing P-Mags pretty much everywhere, and with very good prices attached. Even the 7.62 P-Mags are in stock now at a lot of places, again with low prices attached. To move they would need to stockpile and warehouse a very large supply of product to hold them over, until they can get equipment moved, up and running again. That is costly to have a lot of dead money tied up in product, while the entire company makes a very costly move.....If they even do. My guess is they won't.
This is all about principal. There is no way the Colorado legislature would not allow them to produce and sell their product where it is legal. Mag-Pul doesn't have much to gain here, and a lot to lose if they in fact make this move. It's one thing to make a broad statement like that. It's another to act on it. Especially after they find out what the actual cost will be.
