I have what i thought was a Sig 45 8 round magainze (zipper back) for a Sig P220. I was going thru my stuff and found it, but it does not fit in a P220...... thoughts? I've attached a pic of the mag........ only markings on it were on the bottom and simply said 45 auto.

It's hard to tell from the angle of your photo, but it looks like a 1911 magazine to me. Many 1911 magazines were marked .45 auto on the base plate as well.

^^^ That's what we commonly call dovetailed mag. The zipper back mags really look like zipper. Anyway, yours appears to be the correct German mag for the P220. What do you mean by "does not fit"? It does not insert at all?

i inserts about 1/2 and stops cold. Will not advance the rest of the way into the magazine well.

Turn the mag around 180 and try to insert again?

that worked however the mag does not lock in place and can be pulled free. I took a few more pics. any help is appreciated.

Push the mag release in a little when the mag stops and see if it will insert the rest of the way in.

Looks like a magazine for the European heel release. If you have a P220 with the American style mag release, this magazine will need some modification. The American side release magazines are newer and will have four slots cut into the front. You can try to put the proper slots in this magazine for this to work, or you could buy an earlier P220 that uses these magazines.

Were SIG mags marked like that as well, or just Browning mags?

Concur. Euro mag for heel of hand magazine release.

I think the only mags of this vintage that weren't marked were the magazines sold with the P220s that were originally chambered in .38 Super, but were converted to 9mm for the US market.

These are marked because the multiple calibers used in the P220 required a different magazine profile.

There were also a few with the base pad covering the plate, but these are rare. I'm not sure if the plates used for these had any markings before they were covered over.

I used to own a P220 with the European mag release. I bet that's what it went too. Forgot about it.
