But like many government regulations, their origins have more to do with self-interest than safety.The first proof marks started appearing in 15th century France, and by the 17th century, European firearms guildsmen were heavily promoting their use — and lobbying their governments for laws requiring them — primarily to dissuade competition from non-guildsmen and scare potential purchasers away from un-proofed guns.In 1637, after heavy lobbying from the London Gunmakers Company, a London-area firearms guild, King Charles I issued a Royal Charter setting firearms safety standards. In modern years, they truly do serve that purpose. Re: Sig Sauer Serial Lookup If its a German Sig, there will be a two letter date code, that represents the year of manufacture, stamped on the frame below the muzzle.Proof marks are stamps embedded in certain parts of a firearm following (and sometimes during, depending on the firearm type) its manufacturing to indicate that the firearm has been 'proven' to be able to handle the specific type of ammunition for which it was designed.
Sig Sauer Date Of Manufacture By Serial Numbers AndAs of 2015, the CIP includes 14 member states. Much like reciprocity of modern concealed carry permits between states, some European countries began to recognize each others' proof marks as a high enough testing standard for foreign countries' firearms to be legally imported.Fast forward to 1914, when a number of European countries formed the CIP (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) as a formal standards group to ensure consistent testing among member countries. Over the next few decades, other countries established their own safety standards and proof houses, along with their own unique marks. This is an important fact that will become relevant again later in this article.Sig Sauer P938 Nightmare Price Examples of German Proof MarksHere's an assortment of mid 20th century proof marks used through Germany's (and West Germany's) history:The top row (a) indicates the German (or East/West German, depending on the year) city in which the proof house is located. Because the US is not a CIP member state, foreign guns do not need a CIP proof mark to be sold in the US, nor do US guns need a US proof mark to be sold in CIP member countries. While the CIP and SAAMI do share information and cooperate, neither has a requirement regarding selling in each other's countries. The United States does not participate in CIP, but instead formed its own standards group named SAAMI (Sporting Arms and Ammunition Manufacturers' Institute). Actually, the proof mark is based on the city of Kiel's coat of arms:…which in turn is based on the district of Schaumburg's coat of arms:Coat of arms of SchaumburgThe shape represents a Nesselblatt, or nettle leaf. Many refer to the Kiel mark as a 'squashed bug,' while others have claimed it's an oak leaf. Since Kiel is only 17 miles from SIG Sauer's manufacturing facility in Eckernförde, that's the proof mark you should expect to see on a proofed SIG Sauer. Kiel Proof House MarkThe top proof mark indicates the Kiel Proof House. Proof mark on a West German P220 frameOr on its barrel:On the slide chin (the underside of the slide near the muzzle end), which is the most common location for West German and German SIG Sauers:Proof marks on the slide chin of a West German SIG Sauer pistolTo make sense of these proof marks, let's look at those on the above slide chin. The firearms is then returned to the manufacturer who can legally sell the firearm domestically or export it to another CIP country.The 'nitro' proof mark is also referred to as the 'definitive' (or final) mark of the proof house, as opposed to a 'provisional' mark which would generally only apply to shotgun barrels in an early stage of manufacture, which are tested at proof houses to prevent the manufacturer from continuing work on defective tubes. Provided everything looks good, the pistol is re-assembled and receives the country's CIP proof mark indicating what type of test it passed (the Eagle-N or 'definitive' mark in the case of a German gun), the mark of the proof house, and marks indicating the date of the tests. Technicians then disassemble the pistol and examine it in a dark room using a fluoroscopic lamp, looking for magnetic flux leakage. Walther and Heckler & Koch chose to use 'I' for 8 but skip 'J,' except that you will see a 'J' on an H&K magazine's date code. The proof house in Koln (Cologne), Germany also follows this format. Major German firearms companies such as Heckler and Koch, Walther, and SIG Sauer all used a similar date code format:German gun manufacturers used these letters in place of numbers for date codesJust to keep things interesting, SIG Sauer chose not to use the letter 'I' because it looked too much like the numeral '1,' so J = 8 in SIG speak. Date codes are two-letter indicators of the year that a firearm was proofed.
