You have to reach Level 26 (100.000 Exp needed) to unlock the final upgrade. The best way to grind is the second last level in Wyoming ("A Land Where Game Is King"). takes about a minute and gives you a minimum of 1.700-2.000 exp every round (more if you are good at aiming).
I preferred the 4th scenario of Colorado. Should be something like "Introduction to..." in english. You can get 2.500 Points in a shorter amount of time.
Good guide btw!
