I just recently bought a Glock 19 from
Caswells shooting range in Mesa, AZ. I love it so far; extremely easy to take apart and clean and it shoots great.
Why did I buy it? I need a last line of defense. I'm also going to take the classes to get a CCW permit (even though in Arizona, you don't need one). There's a lot of insane people out there and while I'd like to think I'm beef-caked out, the reality is I'm a computer programmer with a pot belly.
