The minimum requirement per Nevada law is:

The class content (for a Nevada CCW) is mandated by Nevada state law. LIVE FIRE QUALIFICATION AT 3, 5, AND 7 YARDS IS MANDATORY WITH 30 ROUNDS FOR EACH FIREARM.

There is no requirement for 10 yards or "both hands" Anything beyond the requirements of state law is at the discretion of the instructor. If you're in the Vegas area, I suggest that you contact Mike Murray at "A Calculated Response" (888-205-6064) for a fair deal on CCW permits. Mike's a straight shooter. :-)
