Hmmm...
Ordinarily, a good slide-action shotgun in 12 ga would be on the list. Lotsa folks prefer the 870, though I confess I'm partial to the 500.
How about:
good bolt-action '06 (I would say get a nice Mauser/03, but not everyone can get that lucky, I reckon);
1911 (look into ammo selection if you're concerned about stopping anything large; shoulder-stabilized hardball will penetrate 40", IIRC);
good .22 rifle. 10/22 or such if you're a plinker, a good bolt action if you're more a deliberate type. You could go instead for a nice .22 pistol (Mark II, Browning Buckmark, etc), if you prefer them.
Two of these weapons are very definitely sports-oriented, and that's fine. Your guns should fit YOUR needs and activities. If you had these weapons, though, you might also want a final choice that could both be used effectively for hunting, and was quite capable for defensive use at close range. That choice could very well be the
Saiga-12 Shotgun (see Larry Corriea's article re this in the latest SWAT mag).
In your situation, I reckon I'd go for something like:
Glock 19 or 23, or Kahr P9;
CZ 452;
Mossberg 500 Ghost Ring;
Customized 1903.
Another perfectly valid set of choices could be:
Good lever action- I prefer Marlin- in .30-30, .35 Rem, .44 Mag, or .45-70;
Browning BL-22 .22 rifle;
S&W 4" L-frame (.357 would be one fine choice);
Marlin .410.
