While there are apparently people who do use that hold, I would not say that it is common. I have taken clinics/lessons from several All Americans and have watched videos from others and I have not heard that gun hold favoring the straightaway suggested. I like to center my visual field over the gun so I hold the gun where i look. I don't feel a need to look for the straightaway in particular because I find it relatively easy to visually acquire and lock on that particular target.Just wondering how common this gun hold is? Specifically on post 1 and 5. If you setup for a straight away on 1 and 5, all your moves would be either vertical, or to the left (post 1), and right (post 5). Sometimes if Im on the corner of the house and get a straight away on post 1 and 5 I sometimes blow by them horizontally with too much gun movement.
I would be cautious about moving to an uncommon gun hold point to cover up for a tendency to "blow by" straightaways. I think that if you work on visually locking onto the target you could solve that "blow by" problem without making the hard angles more difficult.
In the end you must choose a style and then master it.
