Rost Martin RM1F 9mm 17rd Magazine

The full size RM1F carries 17rd, and this is the flush baseplate magazine that comes with the pistol. Steel body, polymer baseplate, and a scalloped edge on the base that gives you purchase when a magazine hangs up in the well and has to come out by hand.

Rost Martin priced the RM1 line against striker fired guns that cost more, and the magazines follow the same idea - a plain steel stack that feeds and drops free without extra parts to buy or fit. Pick up spares in pairs if you shoot classes, since a full size 9mm goes through magazines faster than most people plan for.
