A possible problem with my new Crosman 357 pistol

A possible problem has developed with my new Crosman 357 pistol. When I break open the barrel, insert the clip, and close it up there is a slight play between the barrel and the frame. As a result, there is a small gap between the clip and the gas outlet . Is this something to worry about? The pistol can be still be returned/exchanged if this is a defect. Please advise me. Thanks.
