Interesting secondary benefit... As my 4 & 6yr old got their turns, I told them they weren't allowed to touch the trigger until they were ready to shoot. I also told them they weren't allowed to point it anyone and it must be pointed at the ground 'til they were ready. After a few reminders, it was quite joyous to see their handling improve to the point where I didn't have to remind them anymore.
I hadn't even thought of that. Great idea. I guess I need to figure out how to lighten the trigger pull on mine so the boy can shoot it.
