Piercing Guns the facts! is illegal and why..
Piercing guns are commonly used in retail settings to perform ear piercings. These gun-shaped devices are designed for piercing tags on rabbits, cows for test results. They are not marketed or designed for use on any part of the body other than the ear lobe, and should never be used on the upper ear. Piercing the upper ear (through cartillage) with a ear piercing gun often results in longer healing times, and possible increased discomfort.
Many professional body piercers discourage the use of these instruments. The major complaint is that ear piercing instruments perform the piercing using a great deal of force with a relatively blunt ear piercing stud. Because of this, it is more difficult to direct the piercing than with a body piercing needle, and healing is prolonged due to the additional trauma involved. Also, the autoclaving of ear piercing guns is difficult or impossible. Because it can not be sterilized , we at Studio 316L do not use it to protect our customers.
