These marks indicate that the shotgun has undergone rigorous testing to ensure it meets certain safety and performance standards set by the regulatory authorities and proof houses. They serve as a certification that the shotgun is safe to use and will function as intended.


The proof marks themselves can vary depending on the country of origin or the proof house that conducted the testing. Common proof marks include the manufacturer’s logo, caliber or gauge information, and symbols indicating the type of ammunition suitable for the shotgun. Some proof marks also indicate that the gun has been subjected to a specific level of pressure testing, ensuring it can handle the expected pressures generated by firing ammunition.
