I recently finished up Wes and Joe's level 4 CCW class. And like the previous three, very safe, very informative, and everyone was given pointers.
As you progress through their CCW classes, the sizes get smaller and the content builds on previous classes.
They encourage you to push yourself in speed while keeping center of mass accuracy. If you are getting "match type groupings", they speed you up. If you are getting "nuns and lawyer's kids", they slow you down and evaluate what you are doing.
Well worth the added cost especially with the added attention to helping people improve their abilities and not just pushing you through
FWIW:
CCW 3 was one handed techniques: both strong hand and weak hand. This included drawing, reloading, shooting, AND malfunction clearing.
CCW 4 was multiple "positions" such as kneeling, face down, sitting, and face up. The day ended with shooting out of a car
Seven people total in the class so there was a LOT of personal attention and lots of individual tips.
