Some additional misc. input:
Handgun caliber debate, e.g. 9 vs 40 is like chicken/egg, conservative/liberal, Israel/Palestine, Christian/Atheist. Good luck finding
The answer.
Neither the 9 nor the 40 is the end all/be all, and like all handguns/calibers, they are a compromise. Both are based upon 4" barreled guns, so choosing a caliber based upon barrel length (3" to 5") is a non issue. Both are poor man stoppers, so shot placement is far more important than caliber. All things being equal, the 40 has more energy, more felt recoil, and less ammo capacity.
While the cost of the guns (9 vs 40) is almost always the same or similar, the cost of the ammo is not. Practice ammo for the 40 usually runs 25% to 35% higher than 9. And that's here in the US where 40 is popular with shooters and LE. In other countries, I would expect the cost differential to be even greater. And then there is the issue of ammo availability. While both are usually available here in the US, I'm not sure how true that is outside the US. I'm quite certain that 9mm is easier to procure outside the US than 40 is.
sig sauer 229 9mm (7 bullet capacity)
The gun you looked at must have been the Sig 239. The 239 has a shorter barrel (3.6 vs 3.9) and lower mag capacity (because it is a single stack mag) than the 229.
IMO ported barrel guns are a poor choice for a home/self defense gun, especially for inexperienced shooters. Ever wonder why so few gun manufacturers port carry guns? Whether or not you train to fire a gun in the retention position is not a reason to purchase a ported gun for self defense. And whether or not you practice shooting one handed with the gun close to the body, there is a real likelihood that is exactly what will happen in a self defense shooting. So my advice would be to skip the ported barrel and practice shooting with the gun close to your body.
Finally Mike, with the prices you list (and assuming you're on a budget), I'd go with either the Glock or HS in 9mm.
