A 10-round factory magazine in 9mm Luger for the Rost Martin RM1F. Reduced-capacity magazines like this one serve two purposes: they keep the pistol legal to carry and use in states and localities that cap magazine capacity, and they are required for some hunting and competition formats.

Because this is an original-equipment Rost Martin magazine rather than an aftermarket blocked conversion, feed lip geometry and follower fit are exactly what the pistol was designed around. Keeping a set on hand also makes traveling across state lines simpler to manage.
