Actually there is a few things to consider before you pick your handgun. You need readily available spare parts, which sooner or later you may need, then there is an accessories issue, you want a gun for which a few extra mags will not cost you an arm and a leg. Then there are guns with polygonal barrels that cannot shoot lead projectiles such as for example Glock, unless you get an aftermarket barrel which will cost you dearly. Then you also might consider which caliber, for example, if you start reloading and want to shoot Glock 22, it is not recommended, because Glock specifically does not have fully supported chamber and a hot load in it is likely to blow up your gun. The gun also has to feel good in your hand, if it won't, you will not enjoy shooting it. Good luck and good shooting.
