It is very fast, we are allowed to modify our equipment all we want on inside but cannot modify outside with exception of grips etc. I compete in what is called gunfighter class. You have to shoot rifle, shotgun and pistol transition from one to another. In my class we have to have a pistol in each hand at same time and simultaneously shoot multiple different targets. It is a hoot! I just use my left eye on left side and right eye on right side like a hammer head shark! Hah! Well not really but it does take a bit of practice!
