Heh - Leigh, he lives in the Americas (South) - we are ALLOWED to be barbaric... anyway, a GREAT pump costs less than an average double.
Although it is stressful to consider 2 only (3 would be nice...), I echo the 12 gauge for long gun and a revolver in 38 Spl, 22 lr, or 32 (Unless 327 Federal or 32 H&R, I would not be keen on the 32). If it's difficult to get 38 Special ammunition, go with the 22 and try to freshen your ammo stock up every year or so if you can.
Revolvers function with any ammunition that chambers - from very light target loads to as heavy as the supplier provides. It is pretty much a part-swapping operation to be able to do that with almost all semi automatics.
Note to fellow gun gnuts - I have and use and like pistols of all sorts - SA & DA revolvers and SA semi-automatic... I have and use a DA semi - like it just fine if I shoot it SA. Personal preference. Anyway, I'm thinking about what HE can best use, not what I like.
