Here's the free advice part: go down to your local indoor range and rent a bunch of different ones -- revolvers, semi-autos, big ones, small ones etc. Of course, do this after you've taken the NRA pistol class, or something similar. While you're doing this, ask yourself what you're going to buy the gun for -- home defense, target shooting, plinking, CCW etc. You'll narrow down the list pretty quick based on your own experience, which is surely the best guide. IMHO, the most important thing is reliability, followed by getting a pistola with a good trigger. Everything else you can work with...
Great advice. Magazines and web sites give you info on reliability and quality - but the true test is how the gun feels and works (within your comfort level for mechanics). That is different for every shooter.
