The Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) is a private organization created in 1926, recognized by the American National Standards Institute (ANSI), and privately funded by companies, organizations, and individuals with an interest in the manufacture of sporting arns and ammunition.

SAAMI serves as the clearing house and reference center for the data need to insure uniformity of firearm critical dimensions and the uniform compatibility of the ammunition manufactured to be used in those firearms.

Firearm/ammunition manufacturers’ adherence to SAAMI manufacturing data is voluntary.

Actually, no. These are the inch pattern lengths of the GO and FIELD REJECT headspace gauges. There is no SAAMI standard for a “NOGO” gauge.

Of course, our friends across the big pond have their own version of a controlling or voluntary mechanism.

For most of western Europe countries (the EU in particular), this is Commission Internationale Permante Pour L'Epreuve des Armes a feu Portatives (C.I.P ). That’s also true for the arms/ammunition manufacturers in other countries who wish to market to those countries who are signatories to C.I.P.

For C.I.P. signatories, C.I.P. standards are supposed to be legally obligatory. The degrees to those obligations have been observed has varied from country to country, and from proof house to proof house, and from time period to time period.

At the risk of blending threads, C.I.P. and NATO have a lot in common when it comes to making and complying with agreements.
