As a company, SIG Sauer does not have a population. If you are referring to the number of employees, there are over 2,300 employees worldwide. If you mean the number of firearms produced or sold, SIG Sauer is one of the largest gun manufacturers in the world, but specific population figures are not publicly available.
No published sn data. Sig offers a letter on their website for a resonable price.
Sig was making a model called the P220. In 1977, Browning contracted with Sig Sauer to produce the gun. It became known as the Browning Double Action or BDA. Browning produced these guns until 1980, when Sig decided to import them into the US on their own.
For 12.95, SIG can give you a nice certificate with the information.
No published sn data that I am aware of
