If you already have real practice with a handgun, the shooting test is trivial. It is only trouble for total novices.
True. My father took the CHL test with a Glock 19 I gave him, and as far as I can remember, he had only fired it a handful of times prior to taking the test. He's a competent shooter, but he only shoots often enough to maintain proficiency - it's by no means a hobby or regular pastime for him. He was also 75 years old at the time and is completely blind in one eye. Passed with no problems.
