Unless you've got REALLY strong wrists, you need to calm down and shoot slower
Guys that shoot fast with pistols typically can't hit the broad side of a barn, but if you take your time to aim, you'll have a higher chance to hit your target sooner
You're not going to learn how to shoot a pistol by rapidly unloading mags at people, you gotta start slow. Once your muscles learn how the pistol reacts, eventually you can fire that thing fairly quickly and retain accuracy.
The trick for me was to always shoot slow, but shoot accurately
