I'm not a Scot, I'm a schoolteacher. So I'm thrifty too!
I took my CHL at the Bullet Trap in Plano and couldn't have been more satisfied.
$120 AND you get two free indoor range passes & a free test fire gun.
Fee included photos & fingerprinting- some charge extra or have you do those on your $$$.
I figured two trips to an indoor range would be worth $30+ and a rental gun the same. That's $60+ in extra value. They have a huge selection of rental/test fire handguns.
