European firearms manufacturing tends to be more heavily regulated than the U.S. industry: governments often set standards on the amount of pressure gun barrels are required to withstand before bursting. Special extra-hot "proof loads" are fired through all guns to indicate their ability to withstand regular pressure loads over long periods of time. This is often done in government-operated "proof houses". When a firearm has been so tested, the proof house marks it by stamping one or more symbols onto the gun. On most SIG-Sauers, the symbols are placed on the underside of the slide just forward of the front of the frame, or near the P230's ejection port.
German manufactured SIG-Sauers typically come with three proof marks. The first is an ornamental crown with an N beneath it to indicate it was proofed with smokeless (nitrocellulose) powder. (The crown-N may also be stamped on the frame following the serial number.) The second proofmark looks (to me anyway) like a "squished 8-legged 2-pincered bug". This is the proof mark for the Kiel, Germany proofhouse. (``It's an oak leaf,'' according to an informed source.) Lastly, the proof house adds a two letter code to indicate the year the gun was proofed. The table at right shows the letter to digit mapping. For example: a SIG-Sauer stamped KB was proofed in 1991. One stamped JJ was proofed in '88.
American-made SIG-Sauers, namely the P229 and P239, are proofed by SIGARMS to SAAMI specifications at the factory. Once proofed, a circle-'P' emblem is stamped into the lower lug of the barrel.

Almost all P229/P229R sold in the U.S. are all-American(slide, frame, barrel) made OR hybrid American(slide, barrel)-German(frame)
If you find an all-German made P229, that's a keeper.
Happy hunting[/U
�� I found�� made in 2000. Barrel proof marks are AA. Shoots great! Thank you all!
