Grip Strength Usual Recommendation - As hard as you can. I find though that comes with some provisos though 1. Without the gun shaking. 2. Can move the trigger finger without moving the whole hand. 3. Can hold for more than a shot or two. I occasionally read a Grandmaster that doesn't advise this and simply says just grip firmly enough to control the gun. When I started shooting a lot more often I found as firm as possible was not a bad prescription. Now with increased hand strength and endurance I find myself simply settling into a comfortable amount of force (which is likely above what I used to be capable of). This amount of force is likely fairly high. If I don't freshly trim my nails before I go to the range I will cut my support hand palm with my primary hand nails. I find more force tends to make me want to muscle the shot (The opposite of what I have been taught). Do I need to keep endeavouring to add even more force and try to train out of the side effects or is palm cutting force enough?
