There is a constant thread of fine motor skills and not relying on them in a gunfight.
Here is and article that I like. http://www.forceoptionsusa.com/node/1427
agree with this article and would like to add something.
Fred argues that training needs to get people to move beyond average. I agree. However, a driver behind the “qualified” shooter approach is budget constraints. The “budget” blinds people and departments in thinking that the level of proficiency needs to be lowered. This attitude is tragic. Proficiency level and cost is not always related. Getting a student to sweep a slide release or mash a magazine release with at thumb can be done in dry-fire. Emphasis should be on providing the student an understanding of measuring and improving their own skill. I’ve seen officer after officer show up to the range and just blast away at their target without any real plan to improve or assessment of their shooting and feel satisfied with just “hitting center of mass”.
