Thanks to this factory 10-round magazine, you can still run a Rost Martin RM1C if you live in a compliant state. 

With a steel body and an anti-tilt polymer follower, you won’t have to worry about its durability or reliability. Although the magazine fits flush, the scalloped base plate makes it extremely easy to remove.
