I agree with this.
Most manufactures have different model#s based on the type of restrictions implemented.
If you try to purchase one that is not designated to your state, they probably wont let you purchase it.
Sometimes its better to just order it from your LGS. Most likely they can get any version and have the magazines blocked.
95% of the time I buy local.
Occasionally, I find a super deal on a used gun.
The LGS can NOT order from the used gun factory, the same exact gun.
In the case I'm referencing, A online vendor had a 5906 in pristine condition for $300 delivered.
I immediately "bought it", paid for it and contacted my FFL to do the transfer.
I then received a call from the vendor and they told me that they're canceling my order because the pistol has "high cap" mags.
I told them to keep the mags, I didn't need them. (I have plenty 10 rounders)
They said they can't do that. I then said they could swap out the mag for 10 rounders, and I'd even pay for the 10 round mags. They wouldn't do that either.
They said their only option was to cancel the order and return my money.

<--- my reaction.
