As the title states, I am trying to find out just what the differences are between these 3 models.

First, there is the cheapest model.

Then there is the "Carry and Range" kit.

Finally, the Pro Series

Only differences I see on the site are the Pro has a lighter trigger and night sights, and the kit comes with a extra mag and few other things.

Also, is Chris from Advanced Arms is reading this... What are the prices?
