Is this a mark 23 mag?

I bought this the same day I picked up my new USP .45 fullsize. I didnt inspect it to make sure it was proper as it was in USP marked package. But upon inserting it into my USP it fits wierd, fits and holds tight but isnt flush. I was just looking at some mark 23 pics and Im now thinking this is the mag for that.

In my USP

Yes, SOCOMS work in all of the fullsize, but not vise versa. You can change the floor plate if you want.

Mark 23 "stepped" floorplate magazine. Replace the floorplate to USP ("flat") and you are good to go.

quick responses, thanks guys.

And then sell the floorplate to one of the guys on here with a 23 and make some of your money back. Or better yet, trade with one of the guys on here who might happen to have what you need already.
