New to me SIG P225/P6 - how can I tell? **Pics added***
Hello -

I picked up a new-to-me SIG P225 in the local fun store the other day and I am not quite sure if I have a P6 or P225. I have asked AI several different ways and I'm leaning toward P225.

The right side of the slide is stamped P225 and underneath the stamp it reads Made In Germany. Underneath that is the serial number (beginning with M646***) which is listed again on the frame.

To the right of the serial number on the frame is some other type of stamp, which is hard to read and hard to capture with a picture. It might be a Z or perhaps a 2, followed by what appears to be an eagle.

Anyone know what flavor of SIG this might be?

Sorry, I am struggling a bit with uploading pics.

As stated above, it's a P225*.

For the purpose of telling which is which:

1- The P225 will be marked "P225", and the P6 will be marked "P6" on of the right side of the slide. That's the most surefire way.

2- The P225 has the typical solid hammer, whereas the P6 has the hammer with that little "hook" at the top rear.

3- The P225 has three complete serial numbers on the frame, slide and barrel. The P6 has complete number only on the frame, while the slide and barrel bear just the last three digits of the serial number.

4- The right side of the P6 slide bears the name of the German state from where it came. For example, you will run across a "NW" or "NRW"-marked P6 that tells you the gun came from Nordrhein-Westfalen. The P225 will have no such marking.


* If you run into a P225 that has the "German Police Pistol" marking on the left side of the slide, know that it's not a P6 but just special production P225 in 2010 that paid homage to the P6. That run was the last of the P225 ever made.

Forgot to address this.

The marking is the eagle over the “N”. They just happened to mark it horizontally, making you think it’s a “Z”. This stamp signifies that the gun has passed the Nitro powder proof testing. That’s the old way of marking things. In modern guns that pass the proof test, the marking is “CIP” over “N”.

FYI, I have had a great experience with board member MaxWayne, who was able to help me with a few SIG P225 magazines. Reach out to him if you need any.

My P6 and my 226 are my faves forever after having a G17 from the 80's, a S&W 469, revolver match guns, S&W 9mm Shield. A narrow sample for sure. Still, I would carry or compete with either. Go, P6! I hope the newer 225's hold up in comparison.

And while we are still on the topic the 225 front cover is something to be proud of. It is a respectable load out any day, any time. Go, P225.

Got the P225 back from getting cerakoted. Cannot wait to fire it.

Working on the embedded pics. Thanks again to maxwayne for the magazines.

Still frame from my favorite film/TV use of the P6. This is from Breaking Bad, complete with prop blood on the grip. My FFL at the time provided a bunch of stuff for the production and he let me examine this exact pistol. It (unfortunately) had a barrel plug welded in place to allow it to cycle when firing blanks.

Kind of a strange question to be asking frankly...if the gun is clearly stamped P225 on it what other logical conclusion could you have drawn other than it's a model P225 (as opposed to a P6).

Lack of a Deformationssporn is the biggest clue Wink

Nice cerakote btw. Mine was already done when I bought it, with a couple idiot scratches but it's one of my favorites.
