It won't take long to learn the basic grip, sight picture and trigger pull. At first you'll likely jerk the pistol downward in anticipation of the round firing, but after a while you'll become used to a gun firing in your hands and get things smooth and steady. There's an endless amount of advice on the Internet, but there's only so much you can learn from behind a keyboard. Since you've had several handguns yet have never fired one... my advice is to JUST DO IT. You'll do fine.
