No. Both the P.04 and the M1900/06 (which used coiled recoil springs) initially came in long frame models. The long frame is identified in the chamber area (between the locking lug of the receiver and the mounting point of the barrel.). The helical recoil spring was a characteristic of the "new model" which followed the original M1900.
