Brand Spankin' New Glock 19

I just bought a Glock 19. I've fired numerous handguns in my attempts to figure out what I want to purchase, and I finally decided on this weapon.

Does anyone have experience with the 19 (or similarly, the 23?) Does anyone carry one concealed? After the requisite training, I plan to get myself a concealed handgun license - frightfully easy to obtain in this great state we call Texas.

I intend to use this weapon for home defense/personal protection. I'm not a cop, though I am ex-military - though that probably accounts for less than you'd expect, as I never handled a pistol in any sanctioned capacity in my time in.

Did I make a good call?
