1) Plinking/Fun
CZ-75B with Kadet Kit, plink with 9mm or 22lr.
2) Utility/Woods
CZ 527 7.62x39mm 527M carbine with low power fast scope or irons, light manueverable, handy, accurate
3) Home Defense/End of the world
Two different answers, home defense would be a nice CZ SP-01 Phantom with flashlight/laser attachment, 19 rounds on tap before mag change. EOTWAWKI, well, I doubt I'd last too long in that time, but I'll take my vz-58 7.62x39mm with Blackhawk chest pouch and many, many loaded magazines.
4) Conceal Carry
CZ P-01 9mm in either HBE or Hazel leather
5) One you can't live with out.
This one will surprise you - Smith Model 10-8, will hopefully stay in the family forever. Inheritance revolver from my stepfather. Very accurate, fun to shoot, goes to my son when I croak. Now I need to find some grips that will let a 10 year old hold/fire it safely - Pachmeyer Presentations on it, came with it.
