Maybe, and the only one I found on GB looked OK. But in that one the P is definitely off center and I don't see how a camera angle could make it look like that.
Just as FWIW, fakers rarely have the right stamps. So they make a circle with one stamp (often simply the mouth of a .45ACP case) then put the P inside it. There is enough variety in the legitimate stamps that if the proportions are right things will look OK.
