Hello all first post here. I recently bought a P 225 which has all the German proof marks on the slide and frame. Proofed in Kiel. However the barrel has no proof marks only Sig on one side and 9mm on the other. I believe it to be a police trade in. In very good condition. Just wondering about the barrel with no proof marks. Thanks in advance

No serial number on the barrel, either? If so, it's a replacement barrel. If the serial number is there but no proof mark, although unlikely, it's also possible that the proof house simply omitted it by error. Proof marking on all major parts are required by CIP law for all firearms made and sold in CIP member states.

Thanks for the reply. A replacement barrel was my thought also but surprised someone replaced the original barrel on a gun that appears to have a low round count

Pretty sure my low-miles P225 doesn't have the serial number or proof marks on the barrel either, FWIW. I'll check when I get home.

There was a brief period (early to mid 2000s) when the P225 had markings just like the P245 (proof mark on the slide but no serial number). This was right around the time the P225 switched over to the newer style of takedown lever. I don't know about the barrels though.

Here are a couple of P225s (not P225-A1) with single serial number (on frame only). One was proofed in 2003 (AD on barrel), the other in 2004 (AE). The 2003 I saved from somewhere on the internet. The 2004 belonged to member YooperSigs. Note the odd out-of-order proof years relative to serial numbers (AD with M653xxx, and AE with M651xxx).

Thanks for the replies. Love the gun. Not the most accurate but probably my fault.

Correction for those none interested; my KF date P225 has 9mm Para on the right side of the barrel hood area, serial number on the left side, and the eagle over N proof on the right side of the locking lug.
