The first CHL class I took was similar in set up and initially sounded odd to me, but after going through the qualification with them, I understood why they had set it up that way. In my experience, they did not want students to do anything other than pick up the gun, aim, fire, set the gun back down - nothing more. I was actually scolded for removing the empty mag after the gun ran dry before I set the gun down with the slide back after the first string of fire. They loaded the mags, they loaded the guns, the students just pulled the trigger. It was the assembly line approach to CHL courses (down to the Glocks in every color, as long as it's black).
You will not have any issues qualifying with the gun, the test is straightforward and easy.
