Base Model with thumb safety?
Where did you get 499 with three magazines, very nice price.
Did a deep dive on Gunbroker and started reading every description starting with the cheapest price and found it in the buy it now section.
How much was shipping and FFL fee?
Well you're going to be very VERY PLEASED with it. I got to play with both the Max-9 and Shield Plus today at a LGS. The trigger in the Plus is FANTASTIC! There is so much difference in the new trigger it feels like Overwatch Precision built it for S&W. Seriously you can't compare the new trigger to the old hinged (elbow) trigger, they're not even on the same playing field. S&W really did something over and above.
