Czech military pistol CZ-52 You can run but you can't hide from this one. the 7.62x25 round will penetrate level 2 armor so it will go right through a car door or window like butter and come out the other side. Not so good for home defence as the bullets go through rather than mushroom in the target.
Accurate to 50 yards.
I take it to the rifle range as the pistol range is not very challenging.

German Police Sig P230 (9mm). Fits in the hand perfectly and is easy to aim well.
Its very ergonomic and comfortable grip, but have to remember its not got a conventional safety lever.

Romanian SKS (7.62x39) is the perfect carbine sized gun for fending off a small army, acurate, fast loading with clipper strips and good range.
A fore runner to the AK47 design.
I imagine this as a post 9 earthquake defense weapon as people start raiding others homes for food and water.

Mosin Nagant 91/30 PU (7.62x52) Accurate to 550 yds, with a scope and makes for a decent low cost sniper rifle for hunting at a distance.

If I ever had to defend myself I'd go for the Sig 9mm. You will never pull the trigger and come up against the safety.
