I have trained with LAV twice in the past, and the more recent class was about three years ago. I have taken a general intermediate type handgun class with him, and the more recent class focused solely on the 1911. As others have commented, he takes a very fundamental approach to pistol shooting, and stresses accuracy. To push skills and abilities, he varies target sizes and distances, but pushes shooters to perform to their best level on the given target. I have “borrowed” several drills from him for teaching my co-workers, and I appreciate his approach in skill building (Of course I credit him when using them).
In my experience, LAV is very approachable and is a likeable guy who wants to make us better shooters. His 1911 class also included a session on detail stripping, cleaning and maintenance, which is something many shooters are not familiar with.
