I am looking into buying my first handgun, what caliber to you guys reccomend? I am looking at the glock 19 9mm. I'd like it to be accurate out to 50yds. I have shot my dads 9mm beretta 92f and wasn't impressed with the accuracy at all!!!
Most firearms are more accurate than their user. Learning the basics of shooting and practice will be much more beneficial to your shooting than just going out and buying a gun built for accuracy. Now, if you are looking for a target gun, you need to look at something other than a Glock. They are combat handguns, and they aren't built for accuracy. Their trigger also isn't the best set up for long range accurate shooting.
The option that gives you the most bang for your buck and will allow the greatest amount of practice is a .22 handgun like a Ruger Mk III or a Browning Buckmark. Each is a very accurate gun, and since .22's are cheap you can practice a lot without burning through your shooting budget.
If you are looking for something with a little more oomph, then I suggest looking into a revolver in .357 Magnum. Their fixed barrels make them vary accurate, most can be had with adjustable target sights, and you can shoot cheap .38 Specials for target work.
