SIG P229 is an amazing pistol, extremely reliable, very low maintenance and extremely accurate. It was my favourite when I used to do pistol range shooting. I used the 9mm, but you can get it specced to .40 or 357 as well.
For old school badassery, the M1911 .45 is a nice piece with a very long track record.
I only own shotguns, a 12 gauge will take care of all your needs.
