Look at all guns then decide on price range. When you start looking at guns you'll key in on features you like and features you must have...Striker or hammer, DAO or SA/DA (location of decocker), constant pull triggers, being able to fire without a magazine in, trigger being able to cock the striker, safety vs no safety, ...seriously just research all types. You may want to spend more, or you may not. Hell you may end up just buying the one you think looks the coolest.
Solid advice. Decide what features are important to you, looking at the major players in the market. I'd look at Glock, S&W M&P, Walther, Springfield XD, Ruger SR, Beretta and Sig (I get confused by all the different Sig models). All the above are solid guns. For every poster on here who loves one of the above, you'll find one who hates it. That's ok because you're looking for the gun YOU'LL love. Try to handle the guns you're interested in. For example, no matter how good a gun the Glocks are, they just don't fit my hand/point naturally well for me (feel like a 2X4). OTOH, the XDs suit my hand well. Even more important, shoot the finalists.
I'd suggest a high cacapity, full size, polymer gun that's striker fired. The Glock 19 is the prototype for these features. Having said that, sometimes a slightly gun (what some might call a mid-size or compact) may fit one's hand better than the full size. For example, a friend of mine loved the feel of the Glock Model 19 (compact), but NOT the Glock Model 17 (full size).
Your choice is very simple -- forgo the Yahoo search -- go buy a Glock 19.
Not a bad choice, as long as the Glock 19 fits your hand well.
Last, depending on your level of experience, consider getting some formal training w/ your chosen gun.
