Half century old, it's about time I own a decent sidearm. Went to a gun show over the weekend, and saw tons of options.

I want something that the ammo is comparatively innexpensive for, but can still be considered a decent defensive weapon. I'll be going after a carry permit, and will likely head to the range a good bit (thus, the need for cheap ammo).

I'm leaning very much towards a 9mm, and the Rugers have caught my eye. Anybody out there own one that can tell me if it's a decent weapon? Also open to other suggestions.
