I purchased a bunch of books, watched videos, did all the drills in the bay at my range and dryfired a ton.
Then the buzzer goes off and I forget targets, run dry, drop a mag, etc.
There is definitely a learning curve.
As long as your safe and go slow, you'll be fine. My main take away is no one is impressed by how fast you go. What does feel nice is hearing alpha, alpha, alpha..
If you can't do it slow, you sure as s#!t can't do it fast.
