Absolutely safety...
Be able to handle your gun in a safe manner..show awarenss of your gun's muzzle when moving left or right, reloading, clearing malfunctions. Keep your finger off the trigger when moving, drawing, manipulating props, malfuction clearances.
You see it often..a new shooter..gets going and loses their awareness of the muzzle or their finger and something unsafe happens...breaking the 180, sweeping themself, AD..
It isn't just new shooters either..I have seen shooters..with years experience with guns; range shooting, NRA instructors, etc..as soon as the timer comes out and a crowd is watching..something happens...
after that...practice shooting As..speed comes over time..but accuracy you need to practice..
have fun..I got hooked on the shooting sports a long time ago..and still have a blast everytime I am at the range.
