Let me explain how this works. I work for several FFL's here in Florida doing gun shows. We can have 100 round mags here if we want. First of all, 99% of gun stores are too small to purchase directly from the MFR. We buy from gun distributors. And they call us all the time telling us what they have. We can take it or leave it. So my boss may need some Glock 17's which normally come with 17 round mags. But the rep will tell us the Glock 17's he has come with 10 round mags because they were supposed to be sold in NY. But all the FFL's in Commie states have all they need. My boss will tell the salesman "I'm in Florida, & everyone wants their Glock 17 to have a 17 round mag". The distributor will reply, we're all out of the SKU # that comes with 17 round mags, so if you want Glock 17's today, they're coming with 10 round mags. Take it, or leave it. So we take the Glock 17's with 10 round mags. The customer buys the gun, & the next day calls us up to complain there's no 17 round mags. We reply that's how we bought it, as the SKU # for the 17 round package isn't available. The customer screams "you didn't tell me the gun came with 10 round mags", to which we reply "you didn't ask, & before you paid we handed you the box, & told you to carefully inspect it before paying. And you gave your nod of approval to complete the deal. Oh, by the way, we do sell Glock factory 17 round mags if you need any". We get AK's with folders that don't fold, with welded on muzzle devices, & other features that should have only been sold in Commie states. But we sometimes have to take them to sell, because the alternative is to get nothing. So in your case, they didn't have the correct SKU # in stock to comply with your states' laws, but they did remove the offending hi cap mags from your gun. I see this all the time, especially with the brisk sales of the last few years. A perfect example is the Keltec PMR30. From time, to time we get them in yellow. We don't like yellow, but it's take them, or wait 6 months to get them in black. It's just the way it's been the last few years. GARY
