You have a rare gun from back when Sig make great pistols––congrats! The 'P' with a circle on the barrel is the barrel proof. If they did, you would find it on the slide, under the barrel, on the 'dust cover.'Īccording to the SigForum link, the prefix AD does make it a 94 gun. IIRC, the P229s did not have proof marks––only 100% German guns did. AD would actually be 03 (also in Growler's post). There is a pic of the proof stamping on page 1 of this thread by Growler67. The serial prefix and proof stamping are two totally different things. The P229 wasn't released until 1992 and only in. Going back means AC is '93, AB is '92 so AA would be '91 (just as. The pattern is lost by 'AM.' My serial number starts 'AD' which appears to be standard for the 1994 year. Was that the first year the P229 was out or was it released in '93?ĮDIT: based on the link on the sigforum () it appears the two letters that start the serial number do, in fact, indicate the year.or at least closely correspond. I did check the mags the pistol shipped with and they were stamped '94. So I guess the letter codes do not apply? The only mark other than the serial # on the barrel I found was a small 'P' (no circle) on the side of the protrusion that the guide rod and recoil spring rest. Found the owners manual.would've thought they'd be right there with it.Īnyway, as best as I researched quickly, the P229 sold in the US was not assembled in Germany.

I changed the grips out to Hogue wrap-around rubberized grips, and can't at the moment find the originals. There are no marking on the underside of the slide. I was unable to find any of the markings mentioned on my P229.
