A factory replacement magazine for the Rost Martin RM1S, holding 15 rounds of 9mm Luger. Rost Martin entered the market with the RM9 and quickly built a following for delivering well-built, American-made pistols with generous standard features, and the RM1S continues that approach in a slimmer package.

Spare magazines are the least glamorous and most important accessory you can own — magazines are the most common source of feeding problems in any semi-automatic pistol, and having extras on hand for practice, carry rotation, and eventual spring replacement is simply good practice.
