Rost Martin RM1F 9mm 19rd Magazine

A 19rd magazine for the RM1F, built on the same steel body as the 17rd unit with a polymer plus 2 baseplate that adds two rounds and a little grip length. It is the higher capacity option for the full size gun.

The extra length sits below the frame, so the pistol handles the same in the hand while the base gives your little finger more to wrap around. Feed geometry does not change from the flush magazine, and it still drops free without help. Black finish, no fitting required, and it is a straight swap for anyone who wants two more rounds in the gun.
