For the OP,
If you like the size, weight and feel of the CZ then get it. You can also check out the Rugers, Sigs and other various brands of all metal handguns.
Since you will carry the weapon a lot more than shoot it I would suggest a glock type weapon. After a 8-12 hour shift you will notice the weight differance.
What on god's green earth do you think your doing?
