He glosses over the type 3 malfunction and doesn't go into how to clear it, which is drastically different than tap-rack. That would be my biggest complaint. I do practice type 1 & 2, but in the field, at the range during competition, the bugaboo has been the type 3. That just seems to be the way Murphy works. So, I diagnose. Good video, good points but I don't own a Glock.
