The 9mm Steyr is an Austrian cartridge designed for use in the Steyr M1912 pistol and was chambered in some Steyr MP34 submachine guns. As with all Starline products, our 9mm Steyr brass is made to tighter tolerance than the CIP standard for this cartridge.
NOTE:
Due to the packaging and shipping process, case necks are often slightly dinged or bent and need to be rounded up and sized to give proper neck tension. New and/or fired cases must be full-length resized or have the expander ball of the sizing die run through the case neck prior to loading.
