Dude you don't understand the glock world yet, dont worry you will. Let my help you with this, if you got the 26 you "WILL" eventually get the 19 period. I promise you, you will. If you got the 19 you "WILL" eventually get the 26 I promise you.
At some point you would have eventually gotten the both regardless of the one you purchased first .
Enjoy it and plan on getting the 26.
That's why I have 2 19s and 2 26s!!
