Depends on the situation at hand as to what I would go for first, and the order.
If I need to get a short list for rapid defense of the homestead, it would be in the following order:
1) Two GI-spec .45's (same brand, nothing fancy so parts interchange) with a spare parts kit.
2) A quality .223 semi-auto rifle. (AR or Ruger ranch)
3) A quality bolt action rifle in a battle rifle chambering i.e. 30-06 or .308. (Remington 700)
4) A good pump action shotgun of the 12 ga. variety with extended mag tube (probably an 870 or 1300).
ammo, ammo, ammo, and more ammo
If the opportunity arose to add to that:
5) A Ruger .44 magnum revolver.
6) A Ruger 10/22 rimfire rifle.
7) A Buckmark .22 semi-auto pistol.

Maybe a GAU-8?
