The fact I wouldn't pick my CZ as my one gun isn't a knock on the CZ, it's a knock on the lack of versatility in a 9mm semiauto.
I can use it for SD, and I can shoot targets with it.
Let me revise that: I'm sure I could use it extremely effectively for SD, and I can shoot one hole targets with it all day at ranges to 10 yards (granted it ends up being a large hole after 50 or 100 rounds, but it's usually one big hole), and score 9,10, and x all day at 25yds.
What I would not want to do with my CZ75B is hunt game, and therefore I don't consider it a good hiking/survival all around gun. If I'm going to have one gun, it will have to do it all. For me, this means a sturdy .357mag at the low end to a .454 casull at the high end.
The only auto I would consider for this sort of versatility would be the Glock 20, but the ammo is a lot harder to find (usually) than .357 or .44mag, and if I could only have one gun, I'd want to be able to find ammo...
