That depends on what you mean by the same.
If your question is will all original magazines for the 1914 and 1934 fit and function in all of the different .32 caliber pocket model variations from Humpbacks to 1934s the answer is yes they are interchangable.
If you are asking if all magazines are the same the answer is no. There are several variations in the bases and the body of the magazines. For example: Round front bases with the Mauser banner are corret for the 1934 model. The bodies started in the white with slotted witness holes and then were blued, then the witness holes were round.
