I agree. What works for one person rarely works for the next person.I love my Glock G19! Perfect size for me, nice round count, and flawless. But seriously you need to handle a few and see what's comfortable for you!
Everyone is correct. You will get a lot of people telling you to check out the XDs, Glocks, and Smith & Wesson M&Ps and they are all correct. These are all great guns. But in the end I agree with Sepe. Go into your local gun shop and feel them all up. You will always shoot a better group with a gun that feels more comfortable to you. I don't know if you are willing to drive or not but if so I know that Roby's Bullseye in Kokomo will actually let you shoot a few rounds on their indoor range if you find a used gun you like there to see if you really want it.
