a couple of things..
get some snap caps and dry fire it about a 1000 times..gives you trigger time..
also squeeze very slowly..most jerk at it..anticipate recoil. You might want to practice with several thousand rounds of .22s ...little recoil but will help you get some trigger time and find the proper balance etc.. also make sure your grip is good...make it comfortable...point as much as aim...
but its all bout practice and practice..you will get better...just takes some time
