attachment 486 is the same gun Sarah Walker used in Chuck vs. The Role Models, and the party against the tiger. and it is misidentified as a beretta 950 jetfire, which it is NOT as you can see in this picture. There was 3 gun continuity issues in the tiger scene. the Gun she pulls in the closet is indeed a jetfire. outside of the closet it this mystery pocket pistol, and outside the room when she puts it back in her purse it is a walther ppk.
Here is another view of the steyr SSPs:
