my hand has a natural shake that comes and goes and is amplified by holding something, also under pressure or stress, and with muscle fatigue. it takes focus, and relaxation to over come. death gripping the firearms makes it worse, and contrary to what some instructors have told me, a soft loose grip improved my accuraccy a great deal over having a tight firm grip. even with my shake, I manage to shoot most handguns very well off hand. another trick I use some times is to have the firearms sights gently fall into the target. and squeezing the trigger at the right moment(not jerking it) I will have to give some ofnthese other tips and tricks a try. great thread btw.
