ProMag Springfield Armory Echelon 9mm 20rd Magazine

An extended 20 round magazine for the Springfield Armory Echelon in 9mm. The high capacity body gives longer strings between reloads at the range or in a training class.

The body is heat treated high carbon steel finished in blue steel and black oxide for corrosion resistance. An injection molded polymer follower rides on a precision wound chrome silicon wire spring made to resist fatigue. Keep one in the range bag or as a spare next to the Echelon at home.
