I suppose whatever an instructor wishes to devote to safety and general handling practices is up to them...Some do a great job explaining and fielding questions in a relatively short time, and others might go into greater detail and depth of discussion...Thats fine as well...
The instructor I use does a good job going over the basics. He told me this weekend that he has "seen some pretty scary stuff" before.
My daughter didn't go out and shoot with the first group of students because she was afraid of one mans gun handling (and questions). He was not aware that in order to qualify to carry a S/A you had to show proficiency with a S/A (happens every class), so the instructor loaned him a Taurus PT92 to shoot with and tried his best to get the gentleman to understand how it worked while we were at break.
My daughter saw all of this...and despite the instructors excellent efforts, she didn't think the guy was "getting it" and it spooked her.
On the shooting range....this fellow had the misfortune of dropping a round on the ground while loading the mag. (it happens), but when he bent over to pick it up, the gun fell out of his nail pouch and landed in the gravel. The instructor looks back over his shoulder at me with a big "half smile" on his face, kind of a "see what I go through" look.
The gentleman did manage to qualify... and in the classroom he seemed very knowlegable about the law (and recent changes). I believe a lot of people do not have the desire (or maybe a place) to shoot, but still want to be able to protect themselves. I have to support that....even though I encourage folks to seek out addtional training/practice.
My own daughter had not shot a pistol in three years because of the demands of school and work. We did put some rounds through her new pistol so she could familarize herself with it. But she shot the course with my .45
So........nows theres another on the waiting list.
